After two weeks of wondering who was trapped in the cell, Grimm revealed in the third episode of Season 5, "Lost Boys," that Trubel is being held captive for some unknown purpose. As the Black Claw mystery gets more complicated as well, Jacqueline Toboni promises viewers won't need to wait much longer to find out what is happening with her character.

"When I came back for the finale, I have been somewhere for that span of time," she noted at Grimm's 100th episode celebration. "She has her machete, but she has a new jacket on. Something's changed, and you know something has happened in my life and I'm part of another world sort of. I've been in that world for quite some time and the audience doesn't know that, and you get to finally figure out where this new turn with where Trubel has gone."


More information will be revealed about Trubel's whereabouts in episode 5, though Toboni cautioned that "I don't even know how much you find out" then. Co-showrunner Jim Kouf said that the Trubel story gets resolved fairly quickly, and events in episodes 4 through 6 will "turn things on their head."

That sentiment was echoed by other members of the cast, including Sasha Roiz (Renard), who said, "It's going to have a few elements this season that will actually send it in a new direction. I don't want to disclose it yet, but there's definitely an injection, another storyline, that will change the direction of the show."

Bree Turner (Rosalee) said the Black Claw storyline is making Grimm a lot more serialized, which is an element that excites her about Season 5.

"Black Claw are now being tied into pretty much every procedural episode we have," she said. "There's a real connective tissue in this season that we haven't had before. Even when we go away from the overarching plot into the more procedural fare there are connecting strings to this violent uprising that's happening. I think it's cool. I think our storytelling is so tight this season. Every season it gets bigger, but I think it also has gotten more refined in a way. Nothing's being taken for granted at all this season."

But though big changes may be on the horizon, most of the characters are still grounded in their present day troubles. "Lost Boys" saw Nick (David Giuntoli) and Adalind (Claire Coffee) grow closer as they bonded over their newborn son, Kelly.

"I think that Nick is so flustered. The ground came out from under his feet. 'Unhinged' would be a word that I would use," Giuntoli said at the 100th episode event. "His baby grounds him and because Adalind seems to be good with his child, I'm going to be good with Adalind for the time being."

Coffee agreed, saying, "They bond over this baby. Everything else is bad in our lives, but we have this baby, so raising the baby and making sure that that baby is thriving is the most important thing, and they do bond over that."

There seems to be something of a Nick and Adalind romance blooming as they start their family, which might be a tough pill to swallow for fans who are used to Coffee's character being a villain. The character has softened since she lost her Hexenbiest powers, and Adalind even had a revelation that she didn't like who she was then. "She just didn't have anything to compare it to, having been a Hexenbiest her whole life," Coffee said. "Now that she does see the other side she can kind of say, 'I would prefer this.'"

Someone who definitely isn't on board with the Adalind/Nick relationship is Bitsie Tulloch, Giuntoli's real-life girlfriend who starred as Nick's girlfriend Juliette until she was killed in the Season 4 finale. "I don't watch [the Nick/Adalind scenes]. I don't care. I don't want to see it -- both as David's real-life girlfriend, and having played his on screen girlfriend for so many years," she admitted, only partially joking. "I can't watch those scenes. I can't do it."

Fans have questioned whether Juliette's death was permanent ever since she was killed by Trubel last season, but as each episode goes by the likelihood of her returning from the grave in some capacity shrinks. The cast still plays coy about Tulloch returning, though it seems like hope is dim.

"It's a magic show, but Juliette has not yet been seen in this season, and we're pretty deep into it," Giuntoli said. When asked whether something could be read into the "Juliette has not been seen" comment -- meaning Tulloch could return in some other way -- he responded, "If we're going to splice it all apart like that, who knows, but no, there's been no Juliette."

Tulloch also stayed mum, acknowledging that "people will stop asking eventually" if Juliette will return.

"All I know is Season 5 is going to be awesome having read some of David's scripts," she said. "They really needed to shake stuff up going into Season 5, going into 100 episode territory. Things needed to change, the stakes needed to be different and higher, and losing such an important character was a really great way to do that."

Grimm will continue to deal with characters saying goodbye to Juliette, Kouf explained, saying, "Because this plays out in real emotional time we try to let every character deal with the loss. You can't avoid somebody, so Monroe and Rosalee have to deal with it, the Captain has to deal with it -- everybody has to find out."

There are other different storylines on the horizon, including a political thread for Renard. "He's kind of getting involved politically. It's going to be very shocking. I think it's going to be very fun," Roiz said. "It's a chance for Renard to spread his wings and get back to Renard. He'll surprise you and he won't at the same time."

Though "Lost Boys" showed off Rosalee's maternal instincts, Silas Weir Mitchell doesn't think there are going to be any babies in the near future for his character Monroe and his on screen wife. "They're definitely teasing that idea. It's part of the conversation. It's in the mix, but I don't think it's really highly likely," he said.

Meanwhile Reggie Lee, who plays Sergeant Wu, is hoping that Season 5 takes the opportunity to delve into the personal lives of his character and Russell Hornsby's Hank.

"Personal stuff and how you deal with what goes on every day with other people -- with your family members -- is a big part of personalizing a story, making it more human, and I do think Russell and I are kind of the human voices of this show," he said. "In that regard, I would love for them to give us a little more of that."
