My thoughts exactly, re: both the desire for further CR and, ha... the fact that he'd probably be a bad influence, but at least this is a place where it might have fewer pertinent repercussions than elsewhere...?

And FAIR ENOUGH, on both the nickname and the abstaining from Jigsaw-ing - Lucas does like setting fires! (And also blowing things up! Even the miniboss in the section of the game he presides over bursts into a fiery explosion upon defeat, and speaking of which, he ICly blasts this during that fight, hopefully Ibuki sufficiently approves)!

In general, though, I will say I love CR between these two and the idea of it keepin' on with keepin' on thus far!
