Agents of SHIELD's Simmons will have a serious case of survivor's guilt when the midseason premiere rolls around.

Three months will pass between "Maveth" and the Coulson's (Clark Gregg) next adventure, but Will's death at the hands of Hydra's Inhuman MVP will weigh heavy on his agent's minds. While Fitz (Iain De Caestecker) will have to deal with the guilt of flambéing the astronaut's corporeal body, Simmons (Elizabeth Henstridge) will be forced to face the fact that Will ultimately died saving her.

"Simmons is grieving," Henstridge told IGN at the 2016 Television Critics Association winter press tour. "She knows that Will has not made it back and that he's gone and that Fitz tried and all that stuff, so she's in a funky place of trying to get over that. She has some survivor's guilt, and she's just so overwhelmed with how amazing Fitz has been throughout the whole process."

Luckily, her grieving process won't put the kibosh on FitzSimmons' future. Fitz's calm approach to searching for Will initially through Simmons for a loop, but it's his caring nature that will help bring them closer together.

"Jemma's feelings haven't changed; they've only gotten stronger," Henstridge said, according to TV Line.
