Also I think the trailer of Arcane season 2 we saw, might merely be Act 1, I heard that Vi would go emo midpoint of season 2 presumably in Act 2, I learned about this on Tumblr, and on Animation Magazine, where Vi has gone emo, fight in illegal street fights, is also drunk and hallucinates about Caitlyn, that mysterious scene was on Annecy, the animation convention from France.
