So what is the new connection between Warwick, Jinx, Vi, and Singed?

At 1:16 Warwick says to Jinx "You were there" and "Let me forget." Seeing as Jinx is someone who enjoys destruction is it possible that she bore witness to it and delights in goading Warwick into doing it again? At 2:30 he speaks to Vi, saying "The fear in your eyes, i've seen it before" and "Zaun needed you," which could speak of a time where Zaun was in need and Warwick was defending it, and Vi wasn't there, and he failed.

Course, Singed is obvious. ;0 But around 1:48 "You can't outrun your mistakes" and "I REMEMBER WHAT YOU DID!", along with "Zaun gave me claws long before you did."
