Marvel's Agents of S.H.I.E.L.D. Season 2 Spoilers: Iain de Caestecker Talks Fitz's Troubles

Fans who tuned in to catch the Season 2 premiere of Marvel's Agents of S.H.I.E.L.D. earlier this week were stunned by the reveal that Fitz (Iain De Caestecker) was actually hallucinating Simmons (Elisabeth Henstridge) throughout the entire episode.

TVLine sat down with De Caestecker to talk about the development in the first episode and to get a glimpse of what's coming in Season 2. Firstly, the site asked about the cause of the hallucinations and, interestingly, the actor was a bit vague in his response.

"Just to make sure I've got it straight: Because of the brain damage Fitz suffered during the season finale's underwater ordeal, his faculties have been compromised to the point that he's hallucinating Simmons being there with him, talking to him. Correct?

I mean, I'm not totally sure what I can say. But yeah, he's dealing with the after effects of what happened to him in Season 1. There are a lot of different things going on."

The site then asked for a preview of what's to come for Fitz in Season 2. "As always with these kind of things we are completely sworn to secrecy, but what I can say is there's some really cool, cool stuff coming up for everyone with the show and with character-specific storylines," De Caestecker replied. "As always with this show, and what Marvel does so well, there are a lot of twists and turns. The show is essentially a lot darker this year. We've got a later time slot [Tuesdays at 9/8c] so it's a lot darker, which makes the danger a lot more real, but it also keeps a lot of the charm that is synonymous with the Marvel world. There are a lot of exciting things that come up."
