Summary: “This is a S.H.I.E.L.D. initiative. So, I guess it’s just me you have to convince.” Coulson shrugs. “But it’s going to take a lot of convincing if it’s not by the book, Steve. The last thing I want is to-”
“Spend time and resources on someone, give them a high security clearance, bring them into the inner circle, and then find out they work for H.Y.D.R.A.?” Steve can’t keep the snap out of his voice. This has everyone on edge. “Yeah, it crossed my mind, too.”
In the aftermath of Project Insight, after Sam and Steve bring in The Winter Soldier, what remains of S.H.I.E.L.D. manages to finally unravel the mysteries of the super-soldier serum. It falls to Steve to find the first two candidates for testing and he's suddenly faced with one of the biggest decisions of his life: who does he bring into the super-soldier family to double its number from two to four? He knows the answer he wants before he starts but he doesn't want to endanger the people he loves. Natasha isn't worried about herself but she refuses to risk Sam's life. Sam's ready for anything-so long as it makes him better at doing what he was made to do: protect this family he's chosen for himself.
