COMPILED JHIN Q+A INFO THAT I FOUND INTERESTING:
-Jhin takes "trophies" from the people he kills (i.e. the maid from the color story "would make a horrible mask" implying that the masks he DOES have are made from dead people and magic)
-Jhin was impressed with hextech when Ionia learned about it
-jhin's father ran a dojo, this part about his life was considered "deep" backstory that shen must uncover
-Before Whisper, Jhin and his father worked "in blades and darts", Odin mentioned that Jhin's father was devoted to "the 100 blades" technique but mentioned that it could be changed in the narrative if it suited them later on
-Khada Jhin isn't the only identity that he uses, but the only one that we know of
-Jhin is ambidextrous
-His obsession with the number 4 started as an internal joke during development but they doubled down on it after it made more sense symbolically and in-game
-despite being completely normal looking, jhin considers himself ugly
-Jhin knows he's "fallable", Odin (jhins writer at the time) said that he's very insecure, searching/fighting for validation, hence why he goes back to the scene of the crime: to see his work's effect, even if it puts him in danger
-jhin would be annoyed by how artless teemo's shrooms are
-seems overpowered but: jhin is good at disguise, he's a GREAT actor, even without a mask he can seem like a totally different person
-kinkou related: the "balance" always refers to the balance of elements, emotions, and the balance between magical and physical
-Jhin started training in daggers at 4 years old HOLY SHIT
-I FOUND A REALLY BIG SECTION ABOUT HIS DAD WOW: his dad's dojo was all about attack speed, think like a ranged attack storm of blades and daggers
-jhin actually hated his dad
-he was trained to attack fast but chose not to, also jhin's lack of natural agility was a huge disappointment to his father
-he would be very mad at someone choosing to not follow a social norm, but also feels like he's above the law
