“Marvel’s Agents of S.H.I.E.L.D.” finally gave fans what they’ve been waiting three seasons to see: a Fitz (Iain De Caestecker) and Simmons (Elizabeth Henstridge) kiss! After too many missed opportunities, the scientists finally locked lips during a passionate moment in Season 3, episode 8. However, FitzSimmons shippers shouldn’t start planning the wedding just yet. Feelings about their future are complicated, to say the least.

Fitz made it clear before and after the kiss that he believes they aren't destined to be together. “We’re cursed,” he told Simmons. “The bloody cosmos want us apart!” After their kiss, he’ll be even more conflicted.

“There’s quite high intensity in that scene, and he’s just kind of like, excuse my French, “F--- it,” you know?” De Caestecker explained to ComicBook.com. “I think it’s just that, and I think ultimately it just makes things more confusing and awkward. It’s not him thinking about it. It has a very sudden, kind of impulse that you get.”

Henstridge revealed that when Simmons leaned in for the second kiss, it wasn’t just instinct. However, the characters may have been hoping that it wouldn’t go so well. “It’s very deliberate, and it’s nice, and it’s kind of familiar almost,” Henstridge added. “That’s when they know…because I think both of them were probably hoping that it would be terrible, because then the situation is just resolved. But it wasn’t, it was really nice. So Fitz says that they’re cursed, because they can’t see a way through it.”

Even though the characters might not be overly excited about this development, other actors like Chloe Bennet (Daisy) were beyond thrilled for Fitz and Simmons. “The FitzSimmons kiss is something that I -- like, that’s one of the biggest things to me this season because first off, I just wanted to see Elizabeth and Iain kiss,” Bennet told IGN. “Since the pilot, I was like, ‘When you guys have to kiss, I will be there.’”

Sure enough, Bennet was watching behind-the-scenes, but she didn’t tell her co-stars because she didn’t want to make them nervous. “Just so you guys know, when you watch it, you might find me creeping in the corner,” she joked.

Fitz and Simmons won’t be the only couple dealing with a complicated situation on “Agents of S.H.I.E.L.D.” this year. Episode 8 also revealed that Coulson’s (Clark Gregg) new girlfriend Rosalind (Constance Zimmer) didn’t realize she was working for Hydra.

“I would not say that it’s done,” Gregg told Entertainment Weekly. “Certainly their relationship got put to a pretty severe test, but it all shakes down in a way that their motives stand up to that kind of scrutiny. There’s nobody more likely to understand the need to get to the bottom of the truth about this kind of thing more than each other.”

Fans will have to tune in to find out if any of the agents’ relationships can survive. “Marvel’s Agents of S.H.I.E.L.D.” airs Tuesdays at 9 p.m. EST on ABC.
