@BergeauxStormie I'm thinking it's cause of two things.
1) She also understood the fact that Vi and Jinx had to separate for the cycle to end.
2) It's a bit like LoL's normal lore, as in there, Vi loses her memory, and Cait never tells her about Jinx being Powder. Could be something similar.
@sut_suty I'm thinking this'll go 2 ways.
- LoL route: Vi loses memory, Cait tells her lies, enforcer Vi and Terrorist Jinx (Unlikely, Jinx is much different to lore in a couple of aspects.)
- A whole new Arcane route that has the sisters reunite to then "enemies" Kinda Batman and Joker.
