If we were hoping for any spoilers for Grimm’s second season, like say what will become of Juliette after that nasty bite, Silas Weir Mitchell isn’t about to let any cats out of the bag.

“Patience is a virtue,” says Mitchell, who plays Monroe on the popular CTV/NBC series.

Monroe is a reformed Blutbad, one of many types of Wesen — monsters that live among humans — in the show that brings Grimm fairytales to life in today’s world.  Monroe acts as a guide and growing friend to Nick Burkhardt, a cop and Grimm, fighter of evil.

We chatted with Mitchell about the show’s popularity, what’s in store for his character this season, Twin Peaks and more.

Were you surprised by the success of the show last season?

A little bit. Not because I didn’t believe in it, I really did, but it’s hard in this incredibly crowded world of media where everybody has their own TV station. That we made enough noise is very exciting because I think that what we’re doing is unique.

The show is often called fantasy meets police procedural. How do you describe it?

This is gonna sound highfalutin, you know, but it’s like a psycho-mythologizing of human behaviour in the context of a police procedural. These people exist in the world, these crazy sickos. When you look at your local news, it’s all about home invasions, child abductions, murders, people setting fires. These creatures exist and these dark tendencies exist in humans. What this show does is it kind of mythologizes them but it’s still very real because we live in a really creepy world, where there are monsters. Monsters are real, the fairy tales are real, they’re only myths because it starts in a place of truth.

Do you think that’s why shows with monsters – vampires, zombies, werewolves, Wesen in the case of Grimm – have gained a strong foothold in popular culture today?

I don’t know if that’s why. Myth is always with us. I think that working in that genre allows you to play with the human soul in a kind of broader, more playful way, rather than being completely hide-bound to reality. You’re allowed to investigate the way the human soul works when you’re working in that broader context. I think that’s why Twin Peaks was so interesting because it was like the real world but it was the real world through a prism.

In previous roles, you’ve played psychopaths and prisoners and here with Monroe, where you’re actually a monster, it’s a little ironic that he's so normal.

I think we all have an inner Blutbad, we all have an inner mouse. Sometimes, you’re very conflict averse and sometimes you want to rip somebody’s face off. And Monroe’s an example of people who live in the world whose inner realities don’t jibe with the outer world. That’s the plight of the Wesen. If you give into it, you become what your ancestors were. And what Monroe probably was before he got his head straight. It’s like a metaphor for the struggle that everybody understands about feeling one way and behaving another way or having an addictive tendency or violent tendency or anger management or whatever you want to call it. It’s a very real struggle.

Will we learn more about Monroe’s backstory this season?

I really don’t know about the backstory. I don’t know what they’re going to do. I’m just trying to keep up. I definitely think that Monroe has chosen to make the world a better place, try to help Nick. Once I realize that this guy is a different type of Grimm and I really am a different type of Wesen, it’s like, "All right, we can work together." Ninety-nine per cent of the Wesen would either run screaming from Nick or try to kill him and I realize, “Wow, this guy is weird and he’s new and he needs help.” And once I decide to help him, I want to do my best. And Monroe definitely imperils himself because of that.

Might there be some romance for Monroe this season? There’s definitely some chemistry there with Rosalee (Bree Turner)?

I think Rosalee is someone where we understand each other in a way. She’s had a hard past and I’ve had a hard past, so yeah, there’s definitely an opportunity there. We’ll see how it develops. I think she’s pretty cute.

What would you like to see for your character?

I guess I’d like to see more of what’s already happening, which is allowing Monroe to get involved in the crime solving, getting in there and not always just being a personal Grimm-opedia.

And there are no hints that you can pass along about what’s going to transpire in season two?

I like people to be surprised. I like there to remain some mystery in the world.

Grimm, season two, premieres on CTV, Monday, August 13 at 10 p.m. ET. Season one is available on DVD/Blu-ray.
