That's a lot less talking than usually shows up in these interaction videos. Even cutting edge, straight to the point Camille had a lot to gab on about.
I recall them saying that Hyena Warwick still has lines not yet implemented, so I'm hoping this is one of those scenarios where they add more lines while he's in the PBE. I don't need Aurelion Sol levels of quips to dispense, but I was hoping for more than one kill line.
Worrying aside, he reeeeeeally doesn't care for the ruling power structures of Piltover and Zaun.
Im 75% sure that Warwick is directly related to the little "gang story" going on between Jinx, Vi, and Ekko. (although Ekko being a part of it is a little questionable now, but still possible)
He has a really interesting taunt towards Jinx.... and the yordles?
And he still looking for the heart of Soraka? Maybe its a cure?
