I'm not surprised Klippy would get a role like that mainly bc I've planned similar roles for him, but that only deepens my belief of him being the Mad Hatter.
Looks like we need his weakness alive. Alice has her uses, for now. I'd hoped that Anarky would be able to do something against Hatter, since he has a deep personal vendetta with him . . . but two roles targeting the same man seems a tad unnecessary.
I'll be sticking with my vote, however. What Klippy said aligns perfectly with my theory about what happens with Hatter at night, but he could certainly be bluffing about his immunity to a lynch.
