every clue in endless summer, explained
technically the title is kinda misleading because some clues simply have no explanation, they just are. still, there’s a lot of pieces to be put together over the three books, and there are clues found in the first book that aren’t explained till the last one. (if you’re confused about the clues, here’s the fandom wiki for book 1, book 2 & book 3.)
before i dive in, here’s some clarifications:
i’ve used mc’s default name, taylor, and neutral pronouns wherever i’ve referred to them. the endless is also referred to by neutral pronouns.
acts 1, 2 & 3 fall under book 1
acts 4, 5 & 6 fall under book 2
acts 7 & 8 fall under book 3
each act has one bonus scene, so if i’m referring to bonus scene 5, it implies to the scene shown after act 5.
ok so unnecessarily long exposition under the cut!
ACT 1
i. tranquilizer dart: found by taylor and diego upon landing on the airstrip. presumably used on the sabretooth, t'kal, to keep it docile. likely done by rourke or his henchmen, but it is also highly possible the endless tranquilized t'kal in order to keep it from killing everyone.
ii. strange creature: a colourful flying seahorse, found by quinn and taylor along the beach in a premium scene. as shown in bonus scene 1, rourke knows of the creature, as he examines it with interest through his binoculars.
iii. weird lights: lights resembling the auroras displayed at the control tower, found by taylor and jake. it is later explained in book 2 chapter 10 by grace, that the lights are caused by the doppler effect, due to the dilation and contraction of time around la huerta. the vaanti call it the lights of vaanu, said to bring them good luck.
iv. vintage wine: if taylor goes to the ballroom with zahra, quinn notes that every bottle in the room predates 1924. as revealed in book 3 chapter 7, the wedding in the ballroom was that of flora and arthur, and group arrived there due to the time anomalies of the island.
v. sharp tooth: found by grace by the pool, near the fence. according to her, the bars were all twisted. presumably belongs to t'kal the sabretooth.
vi. old note: a note found by taylor and diego in one of the upgraded honeymoon/rainforest suites. it was written by flora sullivan to eugene rosencraft, before her wedding to arthur barnaby. it also references neptune cove, where the second half of the island's heart is found in book 3.
vii. pirate coin/wolf symbol: can be obtained either by going to the waterfall with quinn, or by hiking the cliff with jake. the doubloon is probably a remnant of malatesta and yvonne's loot, while the wolf symbol could have been left behind by the endless. the symbol also matches the stamp on jake's dossier.
viii. shoe prints: a set of muddy shoeprints were found by the celestial's shelter. no solid explanation or implication towards who these belong to.
ix. gas mask: found by taylor underwater in the cavern. it looks very old, and as noted by diego, probably from the world war times. it would have probably belonged to kele, a world war ii soldier who paddled his way into la huerta while escaping from the germans.
x. padlock: the unbroken padlock to the burning hangar, which implies that the hangar was unlocked and jake's plane sabotaged. in one of the memories taylor receives from the endless, lila is shown to deliberately sabotage the plane in order to keep everyone on the island, implying she may have done it in this timeline, too.
ACT 2
i. cufflink: lila is discovered pocketing the cufflink in rourke's office, which she probably did to discover his whereabouts later on. in bonus scene 2, rourke is shown to remove all his clothing, including his cufflinks, before he steps into the containment pod. the cufflink can also be used in book 1 chapter 10, where rourke's dna on it reveals a footage video of him complaining about strange occurrences on the island.
ii. dossiers: files containing data on sean, grace, raj and estela are found in the paper shredder, intact. each of them is stamped with symbols of the constellations aquila, cygnus, centaurus and draco respectively. the symbols are left behind by the endless.
iii. whiskey notes: a note discarded by rourke in the vip lounge, referencing the satellite uplink at the la huerta observatory. this is also shown in bonus scene 2.
iv. frying pan: a frying pan embossed with the centaurus symbol on it, which raj says he feels very drawn to. this was also left behind by the endless. he also uses this pan to deflect a sedative dart aimed at taylor in book 1 chapter 16.
v. arrowhead: an amber arrowhead is found lodged inside the king crab's shell, as found by taylor and estela. as the vaanti have been shown to use amber weaponry (as well as in other ways, such as the catalyst idols), it is implied that one of them may have attacked the guardian with an arrow.
vi. dossiers: files containing data on jake, zahra and diego found in the room inside the observatory. they are stamped with the symbols of the constellations lupus, corvus and canis. symbols left behind by the endless.
vii. strange gun: a futuristic gun found by either estela or jake. in book 1 chapter 16, it is revealed to be a tachyon accelerator, used to move objects forward in time. in bonus scene 5, lila refers to the gun as a temporal perforator.
viii. star map: a holographic display of constellations, as seen by taylor and sean as they go up the pod. sean points out that the stars in the sky over la huerta don't have the usual constellations, and that the stars have not looked like this for a million years. this is confirmed in the book 1 epilogue, when aleister notes that atropo's eruption has caused la huerta to go back to the hadean eon.
ACT 3
i. dossiers: files containing data on quinn, michelle and craig found by taylor and diego by the marina. they are stamped with the symbols of the constellations delphinus, pavo and ursa. symbols left behind by the endless.
ii. rourke's ship: if taylor and lila venture into a familiar-looking boat, they will discover it is rourke's ship, the daedalus. he was seen on the ship in bonus scene 1, and he presumably destroyed it along with the other boats on the marina immediately afterwards.
iii. plastic explosive: the semtex explosive is found by taylor in the back of the boat. it's what was used to blow up the other ships in the marina, but this one malfunctioned.
iv. strange shell: a blue-purple coloured shell that repeats the speaker's words over and over. in one of the memories taylor receives from the endless, varyyn is seen tearfully listening to the shell echoing diego's voice, saying 'i'll always love you, varyyn' over and over again as it gradually fades away.
v. telepathic vision: varyyn telepathically communicates with taylor, showing them what would happen if the catalysts didn't go with the vaanti. it is later revealed to be a depiction of atropo erupting, setting the whole world on fire and destroying it.
vi. numbers: in the wine cellar, 1908 refers to a lever to the underground tunnel, disguised as a vintage wine bottle, as well as the cheat code to rourke's arcade game, most wanted 2. rourke also uses an override program on iris called the directive 1908, explained in book 3 chapter 9, which makes iris prioritise the goal she was created for -- to utilise imogen rourke's knowledge on cloning to provide an heir to rourke. another program, directive 8091, forces estela into the omega mech cockpit in book 3 chapter 10, as she is rourke's 'true' heir.
vii. dossiers: files on taylor and aleister are found inside the security centre, both stamped by the endless with symbols of constellations andromeda and serpens. aleister's dossier is newer, printed recently by iris upon discovering that he was aboard the plane to la huerta.
viii. healing plant: leaves of the plant, when wrapped around aleister's bleeding palm, heal it with unnatural speed without a trace. grace and aleister theorize this may be due to some cellular reconstructive properties the leaves may contain.
ix. necklace: worn by varyyn in book 1, the necklace is seen to have time travelling properties, as it brings back jake/estela/sean/quinn/diego back from the dead. it is unknown if the endless facilitated its use or it is associated with rourke.
x. pirate cutlass: the cutlass was forged by malatesta and was stolen from him by admiral higgenbotham, who was presumably killed alongside malatesta's crew in the flashback taylor experiences, by the vaanti. yvonne then stole the cutlass from higgenbotham's corpse, naming it chouchou. it is unclear as to how the cutlass ended up on a display case at the celestial.
ACT 4
i. hydra caduceus: a staff found in rourke's library, which when placed in the statue's hand in the atrium, turns it into a sundial. iris says that the caduceus is the only item in the library she cannot find the origin of.
ii. crimson glove: a futuristic, yet battered metal glove put on display in rourke's underground museum; taylor realises that the person's arm was probably cut off. the glove belongs to the endless, who tells taylor that they learnt very soon that 'the laws of time can be very unforgiving' with reference to their loss of limb.
iii. shotgun shell: michelle and taylor find the 12-gauge armor-piercing shell casing, as identified by jake, during the time loop. he notes that whoever shot this meant business. the shell probably came from one of the arachnids who were on the island searching for jake.
iv. snowy hills: taylor, with either jake or estela, finds snow on the hills and by the lake on a hot and sunny day, indicating time is in disarray throughout different parts of the island, much like the northern and southern parts of the island.
v. wedding ring: a wedding ring is found on the hand of a statue of a masked bride, in the valley of tombs by jake and taylor. the statue is of flora sullivan, and the ring was given to her by eugene rosencraft which she had turned down. it was after this she wrote him the note found in act 1.
vi. tattoo: uqzhaal has a back tattoo of the legend of the threshold. it is the place where yvonne finds the endless in bonus scene 5, and where yvonne, taylor and uqzhaal meet the endless after collecting all the catalyst idols and solving the puzzle.
vii. words on the wind: the voices at the singing cliffs tell taylor that something is coming across the sea, destroying everything in its path. this could either be an immediate reference to yvonne's arrival the next morning, or a vague prediction about the omega mech used by rourke in book 3.
viii. musket ball: yvonne concedes the gold musket ball at sharktooth isle in exchange for their services to find her 'treasure.'
ix. antique compass: yvonne's said treasure turns out to be an antique compass which she tries to conceal; malatesta made her walk the plank for stealing this compass, which she did in order to find the fountain of youth. the compass also leads her to the threshold in bonus scene 5.
x: oath blade: seraxa's gift to taylor for saving taari, saying that debts must be repaid in accordance with vaanti culture. she is shown to threaten the catalysts with this blade in book 2 chapter 4.
ACT 5
i. silver sap: the sap that drips from elyy'stel's tree aids the catalysts to walk in between dimensions. it is the consumption of this sap by eugene and flora that gradually turned them feral and eventually into the vaanti.
ii. deep fissure: if taylor keeps rewinding until they can't go any further, right up to the ancient sea, the catalysts witness the forming of a fissure in the ocean bed. this fissure was caused by vaanu crash-landing on the earth, and it eventually becomes mount atropo, and forms the bubble surrounding la huerta.
iii. the island's heart: one half of the island's heart, which was formed right in the crux of the volcano, found by the catalysts in the base of elyy'stel's tree.
iv. the mask maker: the masks worn by the vaanti bear the name of their maker, rosencraft & sons, 1921. this explains the masks worn by guests at flora and arthur's wedding, which also took place in the rosencraft manor. the rosencrafts were said to be bankrupt, and that the estate belonged to the banks.
v. burning shard: a burning crystal shard that glows green and reacts the same way that quinn did while possessed by the island's heart. it is one of many crystal shards scattered across the island, originating from the crux of the volcano.
vi. mansingh crater: a crater found near the chasm bears the name of mansingh transglobal tech, the company run by grace's mother, blaire hall. it is suspicious to both taylor and grace, as it implies blaire hall was somehow involved with rourke. no further explanation has been made about the crater.
vii. newspaper clipping: a scrap of an article is found by taylor in the elysian lodge, detailing the deaths of arjun and subhanu sethi due to a car accident, also killing their son and putting their daughter in a critical condition. this daughter is lila, and this article implies that rourke (or someone else) was doing a background research on lila.
viii. rourke's note: an old note written by rourke to look into the new junior researcher, as they look familiar. this is most likely a reference to olivia montoya, although it is not known where he recognises her from.
ACT 6
i. rourke's plan: out of agitation, lila blurts out rourke's plan to save the world through a machine at the masada facility. this machine turns out to be the omega mech, and rourke's plan happens to be controlling the world and its people's existence on his whims.
ii. tracking device: a tracking device is found by taylor, attached to the yeti's fur. this was placed there by the arachnid. this tracking device relays location details back to them, as seen in the military humvee by michelle, jake and taylor, where the code name for the yeti is arktos.
iii. garbled message: a distorted voice reveals the date and coordinates of jake's location, received by the arachnid through an anonymous transmission, which is how they came upon la huerta in the first place. this voice belongs to jake himself, who did so using a 'time-phone' in order to merge realities and help them escape through a helicopter from the masada facility.
iv. crashed satellite: varyyn, while talking about shooting stars, says a satellite once crashed to the ground from the skies. it is probably a stray satellite that got caught in the la huerta time bubble, or it belonged to rourke.
v. omega mech: olivia montoya demonstrates rourke's plans for the omega specimen, aka the endless, through a vr headset. she urges the viewer to understand the destruction the specimen, and rourke, are capable of.
vi. missing guests: rourke claimed that the guests at the celestial were evacuated in time at the beginning of the book, but it is shown that he had them put in containment pods. as seen in bonus scene 4, lundgren and the other arachnids were a part of these guests, but were released by rourke upon striking a deal with him to capture jake.
vii. charred skeletons: skeletons of people are found in the flames and ashes at hartfeld, proving that people did not escape the eruption.
viii. havana cigar: lundgren's cigar at the masada facility implies that he was snooping around where he shouldn't, and that he didn't trust rourke. this distrust is confirmed in bonus scene 6.
ACT 7
i. temple/ancient map: if taylor, yvonne and uqzhaal find the endless, they will give the whereabouts of no'ox naj temple to yvonne, where the fountain of youth exists. if they don't find the endless, taylor and yvonne find a carving of the la huerta map on the walls at the threshold, also hinting towards the temple. the whole group meets the endless for the first time in this temple in book 3 chapter 4.
ii. scout: a mechanical spider with a spy camera is found by taylor while they go windsurfing to win malatesta's bet. like the tracker on the yeti, this was also placed by the arachnid to track down their locations.
iii. padlock: a weathered padlock bearing the inscription, 'no land, no sea, no one will keep us apart. flora & eugene, 1920,' found by taylor in a coral reef. after turning down eugene's proposal (the ring clue, book 2), she tried to make it up to him with this padlock and by asking him to show up at neptune cove (the note clue, book 1). when he failed to show up, flora gave up on him and somehow ended up in a forced marriage to arthur barnaby a year later.
iv. pen: a tarnished silver pen bearing grace's name is found in the shrine at no'ox naj temple. it is implausible that she was at the temple, as she was under rourke's custody the whole time. it is also the same pen seen in grace's catalyst idol, returned to her by aleister and ultimately found near professor diaz's car which she had smashed up.
v. silver sap: one of the drinks served at the anachronists' party at quarr'tel is the silver sap from elyys'tel's tree. the creation of the vaanti myth, which is said to have started at a masquerade theme wedding, is that of flora and arthur's, where the former gets shot after confessing her love for eugene at the wedding. in an attempt to save her, eugene gives her some of this sap. this consumption eventually turns them into the feral vaanti.
vi. spirit's identity: the anachronist, clockmaker, refers to the faceless spirit as vaanu. in reality, vaanu is simply an alien being from another planet (the prism dimension) who crash landed on earth when its planet was destroyed. upon communing with vaanu, taylor discovers they are vaanu's creation, made for the purpose of returning la huerta to its normal state, allowing vaanu's departure.
vii. aleister's note: aleister writes a note to grace, apologising to her, and how he feels genuine remorse over his betrayal. he mentions that he hopes to redeem himself in her eyes.
ACT 8:
i. painting: at the rosencraft manor, there's a painting titled 'depiction of the divine' portraying rourke writing the ten commandments dressed in roman attire. the attire probably matches the statue of himself in the atrium, which opens up the sundial to his museum.
ii. communicator: the anachronists provide sean, raj and michelle with antique communicators which lets them coordinate the attack on cetus.
iii. path to the core: vaanu shows quinn the way to the core of the volcano, where the island's heart belongs. this core is the place where vaanu landed on earth.
iv. molten crystals: a crystal orb with claw markings in it, made by the oryctoraptor that dwells inside the volcano. referred to by varyyn as the deep guardian, it is the most reclusive of the four. it is also responsible for the orb found in the cavern in book 1 chapter 5, and possibly the orb that causes the time loop in book 2 chapter 2.
v. the endless' musings: zahra finds a diary belonging to the endless at the base of the volcano, in which they speak of how the sentience of the crystals probably drew the four guardians (cetus, king crab, yeti, oryctoraptor) to establish order on the island, but they were driven mad. the endless also believes it is possible the crystal created the creatures. this is possible, as it would explain the existence of the colourful seahorse, t'kal and furball (although they have not been affected like the guardians have.)
vi. closing words: the closing words spoken by seraxa during the handfasting ceremony, which is customary as 'it was for the first bride and her beloved.' they are the same words that were engraved in the padlock that flora made for eugene.
