1. I do watch Clue once or twice a year. The timing in that movie is incredible. I've referred to it as my favorite comedy a few times, but then I usually remember Animal House.
2. You're right in that someone would have to be motivated to even look for paw prints in the first place. It's unlikely, but I also desperately want short stories about this very thing happening, mostly because I feel the absence of the Alphas heavily.
3. Since Changes, it certainly does feel more actiony. Part of that is the scope of the conflict has dramatically increased; reality is now at stake, rather than just Chicago. Skin Game was different, with reduced stakes, and felt more personal, but nearly every scene devolved into a fight sequence. I enjoy it, because I like the mechanical stuff, but I do miss the mystery aspect. Peace Talks and Mirror, Mirror are unlikely to be small-scale mysteries, but I think Fight Night (or whatever it is truly called) will be a more straightforward, noir-style whodunnit.
