Coulson's team lost one of its key members on Agents of SHIELD, and it wasn't to a bullet.

Agent Grant Ward isn't the upright honest man everyone thought he as. While there have been allusions to his dark and complicated past, his HYDRA allegiance came as a shock to many viewers during "Turn, Turn, Turn."

While Coulson (Clark Gregg) and the rest of Ward's former team have yet to learn of his duplicitous nature, Ward has revealed his true loyalties to the Marvel fandom and Dalton has opened about his new role.

The actor, who changed his Twitter icon to the HYDRA logo following Tuesday night's episode, spoke to Marvel. about what's next for Ward and whether or not he can truly leave Coulson, Skye (Chloe Bennet), Fitz (Iain De Caestecker), Simmons (Elizabeth Henstridge), and May (Ming-Na Wen) behind.

"Try as he might to keep those things in check, I think his feelings--or certain feelings--might have crept up and surprised him. When you're living, eating, and on missions with people, you become part of that family unit. I think that it probably gets harder and harder to turn that off," Dalton explained. "I mean I couldn't imagine doing that myself. Being an embedded spy has to be one of the most difficult jobs I could imagine. Because you have to wear one mask, and not forget about your job, your duty, at the same time. You have to let your guard down in a way, because they need to trust you. But it's a false sense of letting your guard down."

Despite these linger feelings, Ward can't keep a foot in each camp.

"My loyalty to Garrett wins out," Dalton said. "So I have to follow his orders and I have to make some difficult decisions."
