At ABC's 2015 summer TV press tour, "Agents of S.H.I.E.L.D." stars Chloe Bennet, Clark Gregg, Elizabeth Henstridge and Luke Mitchell revealed some not-so-classified information about the show's upcoming third season to Zap2it, including its time jump, Daisy's new outfit and budding relationships.

"There's a big time jump. I feel like everyone's almost come to terms with it in their own way, except for Fitz," Bennet revealed, confirming that Agent Jemma Simmons' disappearance in the season two finale will not go unnoticed.

"It's Fitz's mission to get Simmons back," Henstridge added. "It's a solo mission. What happened was so crazy and there was no trace of her, that what do you do? She disappeared into this rock that goes to liquid sometimes, but we don't know why and we don't know when. I think that the whole team has tried and nothing has worked, so at some point you have to go, 'She's gone, we have to move on.' But Fitz refuses to do that. I don't blame them, but I'm kind of mad."

Bennet's Skye/Daisy Johnson will also have a closer working relationship with Mack (Henry Simmons) in the upcoming season. "We're a lot more comfortable around each other this year. It's like Mulder and Scully," she explained.

"Mack's always been a bit of a skeptic, so him teamed with Daisy's very interesting because Daisy's very gung-ho and gives it a try and very ballsy. So their dynamic is really fun. They've got very fun scenes together. They play off each other very well," Henstridge agreed.

Though Henstridge has already revealed her surprise at the outcome of her season two cliffhanger, she added here that "I thought about it and was like, 'How would they do that? How would they film that?'... I think the repercussions of it will be a huge part of this season, and that will be a bit more of a slow burn, as will the Inhumans, Daisy and Mack are heading up that team."

Henstridge also commented on Lash's appearance in the show. "He's going to shake things up. It's going to be a huge spectacle. We're so honored to be able to have him in the show. It's just huge. I can't even explain how crazy it's going to get."

"3.02 is definitely one of the biggest episodes we've ever done," Bennet teased. "It'll be exciting this season because it's a lot of action, it's a lot of CGI, it's a lot of what makes 'S.H.I.E.L.D.' so big, but at the same time the character dynamics have changed."

In addition to a new haircut, Bennet will also sport a new costume. "It's a really cool outfit, and I hope fans of Daisy Johnson and Quake are really happy with it because we tried to do a nice blend of TV version and comic book version."

Mitchell explained how his character will evolve from season two to three, saying, "I think in that environment Lincoln was very much under the spell of the Inhuman Elders. He played his part in the hierarchy there and he believed in the cause, which then was exposed to be evil. Then in Season 3, it's like, wow, how is he dealing with the events in Season 2? Hence why I was saying he needs to understand where he belongs, who he is and what he stands for."

"[Lincoln] feels differently about what he thinks Inhumans' part should be in society. It's going to be a little struggle between both of [he and Skye] to come to terms with what they both think about how Inhumans' roles in society should be," Bennet added. "But then, you know, there's obviously an attraction there and I know they both like each other, so I think that may get in the way."

"I think it's really interesting teaming Mack and Daisy because, especially from my character's point of view, Mack's the character who knocked Lincoln out at the end of the [season], and obviously Daisy and Lincoln have a bit of chemistry going on, so it's kind of interesting them heading up this team and potentially trying to recruit my character," Mitchell weighed in. "Throwing another [Inhuman] in the mix would be really interesting, especially if there's a thing going on between Daisy and Lincoln."

On the subject of Constance Zimmer, Gregg said, "She's definitely got a lot in common with Coulson. She represents a character who's not someone he comes across every day, who has more in common with him than most other people do."

Henstridge revealed that she looks forward to the day Fitz and Simmons finally get together. "I'm going to love it, and Iain [de Caestecker]'s going to hate it. I already have so many plans of what I'm going to do to him and if we have to kiss what I'm going to shove in his mouth," she shared. "Just anything gross, like garlic -- I was going to say like a worm, but that's rude to worms. Just something gross. It's just a prank opportunity waiting to happen."

Bennet also mentioned how she broke her arm filming during a stunt-filled, one-take sequence and proceeded to film the rest of the season sans cast. "We rehearsed on the weekend on our own time and we put in the hours not getting paid just to do it for fun, and it paid off, I think. I did break my arm during that take on camera. Then I had to finish the season with a broken arm and do all of the rest of the fight sequences with a broken arm. That was tough."

"I hid it by just dealing with it," she explained. "I couldn't wear a cast. I had two hairline fractures in my elbow. I had to have a cast to take on and put off. The hardest one was when I fought May. In 'Afterlife,' I have a fight with May in one of the last episodes, and that one was really difficult because my arm was hurting a lot. My arm was really broken then, and I'm stubborn enough to not let my stunt double do as much as she should have."

Starring Gregg, Bennet and Ming-Na Wen, "Agents of S.H.I.E.L.D." season three premieres Tuesday, September 29 at 9 pm EST on ABC.
