Bitsie Tulloch is back, and certainly more badass than ever on Grimm. After being unceremoniously shot by Trubel (Jacqueline Toboni) at the end of Season 4, viewers learned that Juliette wasn't actually dead but instead being reconditioned by the kind folks at Hadrian's Wall.

In the Season 5 midseason premiere, we were introduced to Eve, the harder, tougher and wholly less villainous character that Juliette has been turned into. If her heart-to-heart with Nick (David Giuntoli) didn't clue you off, she's not feeling the same sort of love that Juliette once felt for her former beau. So what role does she have to play in the show now?Tulloch got on the phone to talk about the introduction of Eve, how the other actors on the show have been handling her new character and how she's felt about the new on-screen romance between Adalind (Claire Coffee) and Nick.

Psychologically she still has a lot going on. That's sort of my own personal work as an actor. There's a tremendous amount of focus and control in her life now because she doesn't want to think about anything Juliette experienced. She feels completely disconnected from Juliette and all of the people that Juliette loved and interacted with. Right now, it's a new phase because, yes, she is the most powerful weapon that Hadrian's Wall has.I really like the analogy of her putting her back in her room [like a weapon], and she's happy to do that because she doesn't want to really risk devolving back into Evil Juliette's kinds of things that she could do. Honestly, we thought Evil Juliette was powerful; Eve could have killed her with one look. There's some really fun scenes coming up where you see Eve training, working out or whatever in her room. It's almost as much a mental exercise than anything else.I can't speak for the producers or the writers. I personally, right now -- and we're shooting episode 16 -- she's on a mission, and nobody is going to take her off course. If there's any feeling there, you're going to see half a beat of her looking at him. It's so contained. And if she feels even a little glimmer of anything for him, she'll look away and start doing something else. She's just not going to go there.Somebody asked, "Was she angry about Adalind and the baby?" and I'm like, yeah, Juliette was, but Eve does not really have an emotional attachment to them. She wants to protect Nick because she feels like Nick is going to behoove Hadrian's Wall and is an asset. Whether she wants to protect Nick because there's still love there remains to be seen.[laughs] I was so careful about not tweeting over the last seven months while I was keeping it a secret, but I did watch an episode over at Bree [Turner]'s house once and I was saying whenever there's a Nick and Adalind scene I basically shut my eyes and pretend it's not happening. [laughs] But here's the funny thing: people think I would care. People ask me, "Is it weird seeing David with Claire?" and I'm like, no. David's an actor and Claire's my friend and she's an actor too. That's not weird. [Editor's note: Tulloch and Giuntoli are dating in real life.]It's weird with Juliette. Shaking a character that I've played for four years, that's a long time to really get in a psyche and a headspace and bring a character to life. Juliette couldn't watch those scenes. I'm perfectly capable of it, but it's really Nick and Adalind together that would make my blood boil insofar as Juliette's blood would be boiling. It's totally fine because everyone's friendly, but in the very beginning I hadn't quite gotten rid of Juliette yet, so there was some, "Ugh, that was supposed to be my baby!"It's really cool because everyone's having different reactions to Eve. It's fun to show up on set and see how Silas [Weir Mitchell] has decided Monroe is going to react to Eve. Obviously it's also partly scripted. I would say I've worked with about half of the other series regulars, and there are still a couple people who Eve has not yet had any interaction with. That's coming up. We're at [episode] 16 now, so I think by 17 or 18 Eve has had at least some interaction with all the former members of her life.Yeah, particularly David. I think David did a really, really great job. He was the first person I really worked with. He, I think, just did a really tremendous job of [capturing] "Am I looking at flesh-and-blood? Am I looking at a ghost? Am I going crazy? Who is this? What is this human being that sounds like Juliette and looks like Juliette but it's not her?"
