'Grimm' Season 3 Spoilers: Alexis Denisof Nabs Role in Upcoming Season

Alexis Denisof of "Angel" is joining the cast of supernatural characters in NBC's "Grimm."

TVLine confirms that "Grimm" co-creator David Greenwalt reached out to Denisof to join the show's third season. Greenwalt previously worked with Denisof on the show "Angel." Denisof will join the dark, fairytale thriller to assume the role of Viktor Albert Wilhelm George Beckendorf, Renard's (James Frain) shrewd first cousin. 

In addition to Denisof, Manny Montana of "Graceland" is joining the series to guest star in the role of David Florez, an ex-marine who served in Afghanistan. Florez is quick-tempered and suffers from Post-Traumatic Stress Disorder, an ailment suffered by many veterans. 

TVLine also reports that Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) will be getting hitched in season three. The pair's romance blossomed in season two, despite the fact that they are two very different creatures. (Monroe is a wolf-like Blutbad and Rosalee is a fox-like Fuchsbau). 

The pair may have a hard time convincing their families that they will be a successful match. Executive Producer David Greenwalt said that Monroe's family is not as progressive as their son. "They think Fuchsbau like Rosalee are for eating, not for settling down with," Greenwalt said. 

Greenwalt and co-executive producer James Kouf said that Nick's (David Giuntoli) comatose stay in the box, which was shown in the season two finale, will make him "dangerous."

"He's definitely going to the dark side," Greenwalt said. "And he may get another face of green spit before it's over." 

Guintoli commented on the future of his character while at Comic-Con. The actor hinted that Nick will have a different attitude once he wakes up from his zombified state. "It's very nice to get to be angry," Giuntoli said. "There's gonna be a lot of fighting in this first episode [back]."

They also shared that Wu (Reggie Lee) will be shaken up by an encounter, and Hank (Russell Hornsby) will become romantically entangled with his supernatural physical therapist. 

Grimm's third season premieres on October 25 on NBC.
