Warning: Full spoilers for the episode below. Even though this Mad Hatter storyline might spell the end for Michael Chiklis on Gotham, I'd much rather the show be doing something interesting with him, like they are now, than letting him sit stagnantly on the sidelines like they did for most of Season 2. In "Blood Rush," the madness-inducing qualities of Alice's blood finally took over and turned Barnes into a killer vigilante.
