Hm.
Zenge only even mentioned cubs twice, so not like he was pushing hard there. alley wasn't sussing him either, she had him in neutrals.
I don't want to believe that cubs would N1 NK Zenge after he died when he did in Shots. Of course, the problem I run into with that thinking is the only person in this game who I can see NKing Zenge N1 right now, given previous games, is Cyndia because she wouldn't know. Otherwise, it has to be someone I want to believe wouldn't do that, because the rest of the group has been playing regularly.
Also kind of interesting to me, though almost definitely just coincidence, that the NKs so far have been the Bioshock pack.
