Honestly, he had absolutely no idea why Fury had decided to reassign him to a team instead of letting him do what he did best – work alone. Sure, finding out that Coulson was alive was a thrill, and he definitely didn't mind the promotion that went along with being a member of the team.
But still. It was exactly that – a team. And he didn't exactly work well with others.
When Skye joined them, helping them look for Peterson, he was even surer of the fact that this really wasn't the place for him. Of course, the fact that Coulson happened to dose him with truth serum and allowed Skye to grill him didn't help at all.
But then they were in the middle of a train station, and there was a rifle in his hands and a possibly insane, definitely super powered human was standing there screaming at Coulson. And as he aimed, ready to fire the moment this turned ugly – and he knew it would, there really was no other option – something in him settled.
Before, he'd helped nameless people, never really knowing just whom his actions were affecting. But here, he had seen the people fleeing, people who would have been in danger if it weren't for S.H.I.E.L.D, for this team.
He still wasn't sold on being a part of a team and trusting people who weren't himself, but he could work through that. As he let the bullet fly, he knew for certain that this was where he belonged.
