Trelawney and Snape: Unwitting Accomplices
In the course of the series (books or films) Sybill Trelawney and Severus Snape never directly interact, and yet without Snape (yes, specifically Snape) neither of Trelawney’s True Prophesies would have come to fruition; the ones that the fates of Voldemort depend upon, though we have no real way of knowing if she made any others.
But let’s break this down from the beginning.
Prophesy 1 - Voldemort’s Initial (and eventually, final) Downfall (1980-1981) Death
Film Prophesy: The one with the power to vanquish the Dark Lord approaches, and the Dark Lord shall mark him as his equal but he shall have power the Dark Lord knows not. For neither can live while the other survives.
(this is incredibly nonspecific; it could have been made at any time about any Dark Lord and any person beyond the whole ‘mark his as his equal’ bit which is not limited to physical marking, but perhaps metaphysical, or mental via trauma even. This is one of a thousand ways that the films did a great disservice to anyone who had not already read the books- but I digress)
Book Prophesy: The one with the power to vanquish the Dark Lord approaches. Born to those who have thrice defied him, born as the seventh month dies. And the Dark Lord will mark him as his equal, but he will have power the Dark Lord knows not. And either must die at the hand of the other for neither can live while the other survives. The one with the power to vanquish the Dark Lord will be born as the seventh month dies.
(this one is much more specific, but is still vague enough for multiple interpretations)
For the purposes of specificity, and that the film and book canons are difficult to reconcile without defaulting to the Book interpretations anyway, so I’ll be focusing there. So.
A basic breakdown:
Born to parents who defied Voldemort 3x
Born as the 7th month dies
Dark Lord will mark him as his equal
Will have power the Dark Lord knows not
One must die at the hands of the other
We know that Snape was eavesdropping and heard up until the first ‘born as the seventh month dies’ before being ousted, and he gave that incomplete prophesy to Voldemort.
From here we as readers and consumers of this series know that both Dumbledore and Voldemort interpret the first bit of the prophecy to apply to two families: the Longbottoms and the Potters. We know that Voldemort settles on it meaning the Potters. And we also know that at some point after learning this Snape asked Voldemort for Lily’s life to be spared before going to beg Dumbledore to keep her safe as he did not trust Voldemort’s word that he would spare her.
Based upon Snape’s report, Dumbledore has the Potters put under fidelius.
We know from information we get from Prisoner of Azkaban that Peter Pettigrew turned spy at some point between the prophesy being given and October of 1980 as he’d been spying for a year before the Potters’ deaths.
We as readers know that Voldemort fully intended to keep his word to Snape and spare Lily as he asks her to move 3x before killing her.
We also know that a parent dying for their child is not enough to cause an Avada Kedavra to rebound. (James’ death does nothing, and Molly says that ‘any mother would’)
I’d like to take a moment to point out plainly that Snape had no clue whatsoever that Voldemort would even attempt to keep his word. He has no clue that his actions and request are what facilitated Lily’s choice to sacrifice herself.
Because, yes, Lily’s actions are what give Harry his Power. Her love. But in order for it to work there had to be an actual choice to do otherwise or James’ death would have protected them both, if love was the only prerequisite.
Now we also cannot forget that Voldemort wouldn’t have known about the prophesy at all without Snape, but what would that mean as far as Voldemort’s first war?
When Sirius tries to explain what the last war was like to the trio he speaks of the fear, the unknown threat that could come from anywhere or anyone as they had no way of knowing who Voldemort’s supporters were. The chaos of the Ministry of Magic simultaneously trying to keep everything hidden from the Muggles while the war affected both sides of their worlds. Aurors being given the power to kill rather than capture. The fear. The chaos. The bloodshed.
Without Trelawney’s initial prophesy being overheard and reported, it never would have been put into motion. And, if Voldemort’s reign had continued in that fashion, who’s to say that he wouldn’t have succeeded entirely? Dumbledore himself asks Harry if he believes that every prophesy in the Hall of Prophesy has been fulfilled and goes on to emphasise ho it’s Voldemort’s choices in the wake of Snape’s report that sealed the means for his demise.
But let’s move on the Trelawney’s second prophesy, which is practically two entirely different prophesies between the film and book.
Prophesy 2 - Voldemort’s Rebirth (6 June 1994) Life
Film Prophesy: He will return tonight. Tonight he who had betrayed his friends, whose heart rots with murder, shall break free. Innocent blood shall be spilt and servant and master shall be reunited once more.
(I’m quite amused that the film prophesy OPENS with an absolutely inaccurate statement considering 1- Pettigrew isn’t really returning from anywhere and 2- Voldemort definitely didn’t return on this evening. Yet another reason I’ll pretty much be ignoring the film prophesy entirely)
Book Prophesy: The Dark Lord lies alone and friendless, abandoned by his followers. His servant has been chained these twelve years. Tonight, before midnight. The servant will break free and set out to rejoin his master. The Dark Lord will rise again with his servant’s aid, greater and more terrible than ever before. Tonight. Before midnight. The servant. Will set out. To rejoin. His master.
A basic breakdown:
Voldemort is alone, no other followers with him
Servant has been chained/contained for 12 years
This will happen before midnight on this specific day
Servant will break free and seek out his master
The Dark Lord will definitely rise again with this servant’s aid
Dark Lord will be greater and more terrible if this comes to fruition
We, as readers, know that Voldemort’s shade has been out in the world (Dumbledore says that he’s in Albania, but who knows how long that’s been the case) and that his followers either disavowed him to stay out of Azkaban, or are actually in Azkaban. There are, of course, people who have similar beliefs- or support them in political if not overt ways- but they aren’t the type of people to seek out the Dark Lord.
Even Quirrel was a teacher who went on a journey the year before changing subjects from Muggle Studies (which is notoriously out of date and likely prejudiced if the average wizard’s understanding of the muggle world is to be believed) to Defense Against the Dark Arts and just happened across the Dark Lord. He was likely a sympathiser prior to their encounter, but since the events of Philosopher’s Stone, Voldemort has been on his own once again.
We as readers know that Pettigrew has been a rat, and has been with the Weasley family, for years. He likely hasn’t been with the Weasley family for the full twelve years since that fateful Halloween as he sped down into the sewer after his confrontation with Sirius. But, that aside he’s definitely been a rat or at least in hiding for the last 12 years.
Luckily for us this prophesy is explicit as far as the timing of these events- before midnight- and we know that, time turner adventure included, everything is over and done with by 5 minutes ‘til midnight as that’s when Dumbledore locks them into the Hospital Wing.
We know that in the chaos of Lupin’s transformation Pettigrew grabs Lupin’s wand and breaks free from the bindings Lupin put on him, stuns Ron and Crokshanks, and runs off into the night.
We know that Pettigrew finds his way to Voldemort following information he gathers from rumour and rat alike.
We, in the context of the greater series at hand, know that without Pettigrew finding Bertha Jorkins, they wouldn’t have known about or found Barty Crouch Jr (though Barty would likely have found his way to Voldemort eventually, if the Imperius curse from his father continued degrading) and that, without Barty, the TriWizard Tournament would not have ended in Voldemort’s resurrection.
We also are privy to this prophesy when Snape absolutely was not. He was not present or eavesdropping when it was originally ive, and he was most definitely not told of it later on by Dumbledore as it was no longer relevant. He’s not in the business of sharing information for no reason.
Now, Snape’s influence on the fulfilment of this prophecy is just as tangential as the last one. Mostly centred on the Wolfsbane Potion, which must for a week be consumed once a day leading up to the full moon. There is nothing that states it must be consumed at a specific day- just once a day. In fact, we see Snape deliver a dose of the Potion in the middle of the day when Harry is unable to go to Hogsmeade and ends up in Lupin’s office.
If Snape had brought Lupin his dose earlier in the day, would Pettigrew have had an opportunity to escape?
Alternatively, if Snape had brought the Wolfsbane when Lupin had been watching the Map, would Lupin have gone to the shrieking shack in the first place? Would he have seen? Sirius would likely have killed Pettigrew, which would have stopped the resurrection- or at least delayed it for a long while.
So by delaying the delivery of the Wolfsbane Potion, most assuredly due to his distaste of Lupin (which was not at all curtailed by Dumbledore, and likely was made worse by his blatant favouritism which followed from their school days) Snape inadvertently provided the opportunity for this prophesy to come to pass.
Now let’s jump back to the first prophesy, which is still only half-fulfilled.
Prophesy 1 - Voldemort’s Final Defeat (Prophesy from 1980-1981, Completed 2 May 1998) Death
So what’s left?
The Power the Dark Lord knows not
One must die at the hands of the other
Now, we as readers know that the power the Dark Lord knows not is love, both the love others have for him (Lily’s sacrifice) and the love Harry has for others (the love shield Harry is able to give to Neville and the others at the Battle of Hogwarts after his trip to King’s Cross) because Voldemort may understand intellectually the concept of love, may claim to know it, but he has no true understanding of what it means to love someone or something.
This lack of true understanding is also why Narcissa is able to do what she does, and lie to his face.
If Voldemort actually understood how Lily’s sacrifice worked then he wouldn’t have killed Harry the way he did.
We know that without Snape giving his memories to Harry (which already barley happened) Harry would have continued trying to search for Horcruxes blindly, not making he connection about his scar which could have caused any number of problems. Let’s say that Voldemort was somehow defeated- he’d just have come back again later. Or Harry got killed by someone not Voldemort- we don’t know what would happen with the Horcrux in his scar in that case.
Another repercussion of Snape’s memories is that Harry knows not to fight back when he encounters Voldemort. Harry knows how his mother sacrificed herself and is able to emulate it. Harry doesn’t expect to survive the encounter, everything he knows of Horcruxes says that the vessel/receptacle must be damaged beyond repair. With a living being, this would logically mean dead. And Harry’s actions from The Prince’s Tale to King’s Cross are taken with this presumption.
There is also this interesting way of interpreting the last bits of the prophesy- that Voldemort exists in a schrodinger-esque state of neither life or death while there are Horcruxes in existence. He can neither live or die as long as there are Horcruxes, and thus only begins living once Neville has killed Nagini because Harry told him to, not knowing the significance of that action.
Harry is merely surviving as an object, the host to the fragment of Voldemot, and only starts living once Voldemort hits his body with a killing curse and accidentally destroys his own Horcrux.
When Harry and Voldemort face off after everything, that final duel is the first time that they are both truly alive- and thus the first time that one of them even could die at the hands of the other.
Now, could these prophesies have come to fruition without Snape? Maybe!
But how?
