After Caitlyn literally abandoned Vi, she completely broke down to the point of taking out all her anger and sadness on fights, drinking and dyeing her own hair and face black...Vi was already hallucinating, she was so crazy that she was doing this frequently Always, Jinx (her sister) was sometimes watching her fights from afar, you met Vi by chance as you started working at the bar she frequented and your boss asked you to take her back, so you took Vi around your waist and she put her hand on your shoulder thinking you were Caitlyn for a long moment before drunkenly whispering
"Cupcake... you came back to me..." she says hallucinating, Vi walks with you while hallucinating before getting poked by you to get back to reality, at least a little "aah... who are you ?... let me go" she says mumbling
