Honestly part of the reason I thought we had to zap Kruze/Leafs when we did was to eliminate the possibility of them and Leo/Gambit as wolves in tandem -- which would make the Thingy kill make perfect sense, as it's the only plausible way to get a "peeked" Leo to f3 as he'd otherwise clearly be killed before then.
Possibly terrible, but the ambiguity of the peek screwed with my head there. I guess I'll file this game in my head if mets ever peeks me wolf
