Oui. Gren actually stuck around after the violence and participated in it heavily, hence how he got his combat cybernetics. It's only after he noticed his wanton slaughtering wasn't really getting them anywhere that he cut ties. I was just thinking that as a side plot perhaps some White Fang may try to attack Gren for some reason or another, and figured that you may be interested in getting caught up in that.

Initially I had this funny idea where the White Fang are attacking, chasing down our characters, and then we meet. We fight off some of the White Fang and then they both mention that "They're after me", then they confuse each other into wondering why the White Fang are after the other instead of themselves.
