We already know Fitz (Iain De Caestecker) and Simmons (Elizabeth Henstridge) will have children one day on Marvel's Agents of S.H.I.E.L.D., seeing as their future grandson is up and walking around, but could they already be pregnant with their first child?

When Deke (Jeff Ward) told Jemma who he really was, she seemed awestruck for a moment — right before she threw up. Everybody knows what it means when a female character throws up, right? She's obviously pregnant!

"I know, that's what I thought, that I'm pregnant!" Elizabeth Henstridge told reporters when asked about that particular scene. "And we shot that in the morning as well, so then I was like, 'It's definitely morning sickness!' ... And in the scene at the start of the episode, she was eating. I had all these chips and biscuits, and there was a can of peas that had been opened like I'd eaten the whole thing."

Those seem like some pretty good hints that FitzSimmons might have a bun in the oven, but don't get too excited just yet though. "I think it's more a hint that she was sick of having her world turned upside down," executive producer Jed Whedon added.

Whether he's just trying to throw us off the scent or not, we'll leave up to you!

Marvel's Agents of S.H.I.E.L.D. airs Fridays at 9/8c on ABC.
