Michael Chiklis’ character  Nathaniel Barnes is going to undergo transformation in “Gotham” Season 3, and it’s largely because of Alice Tetch’s (Naian Gonzales Norvind) blood affecting him.

Chiklis told Blastr that his character is actually in a weakened position this season, given everything that’s happened to him and the police force last season.

“Well, when he first appeared in Episode 1 of Season 3, he was actually very diminished. He was badly, badly injured, and really hurt and weakened. He looked like he wasn’t going to survive, but he did, miraculously,” said Chiklis. “But he’s not healed. He is not coming out of it. Things are spiraling out of his control around him. He really doesn’t have the authority he once had.”

Barnes is trying to stop Jim Gordon (Ben McKenzie) from spiralling out of control, but he’s “ineffectual” in that sense as well. He's also disillusioned because Penguin was elected as mayor of Gotham City. All in all, Barnes is frustrated and weakened, but things are going to change.

“Well, I want to tease this without ruining it. Something changes the dynamic entirely in his own self, and his own body, and his own mind. And that changes everything for him, inexorably,” he said.

With the way things are going for Barnes, he might just end up being the most tragic character in the show.

Chiklis revealed to Comic Book that even before he took on the role, he already knew of this big twist that will happen to his character in Season 3. Chiklis said it actually helped him develop his character Barnes better.

“I knew that I could be a particular kind of man, knowing that I didn't have to worry about it becoming too one note or flat, because I was going to go somewhere,” he explained. “That's the wonderful thing about being in television anyway, because you get to explore a character over the course of many, many hours instead of the context of a two-hour film. There's some really cool stuff coming.”
