Coulson's Agents of SHIELD team is used to being kept in the loop, but the new director may drop his personal loyalties in season 2.

Phil Coulson's (Clark Gregg) recent promotion will put him in a precarious position when the ABC series returns. No longer just the leader of his own team, Coulson will have more irons in the fire than ever - and more secrets, too.

"He went from a guy who was having a lot of secrets kept from him last season in a way that made him suddenly hate secrets - although he'd been keeping them him whole adult professional life - and [he] didn't feel comfortable keeping them from the people he cared about on his own team to the Director of SHIELD [who has] no choice but to keep secrets or he's going to cost people their lives," Gregg told Buddy TV at the 2014 San Diego Comic-Con.

Keeping information from his team probably won't work out particularly well, and Gregg hopes Coulson won't have to keep it up for long.

"The job he's got is bigger than any personal loyalties so it's be very interesting to me too see how much of that bigger-hearted Coulson that came back to life is allowed to function in that job," Gregg said.
