He was helping me try to get closure after I found out it was another SHIELD agent who sold me out and allowed HYDRA to capture me and brainwash me into doing what they wanted. Grant saved me from them and then SHIELD locked me up and threw away the key when he left me with them and the agent responsible for me getting captured in the first place was there. So I took the first available opportunity to get out of there and took her with me so we could try and get her to admit to what she'd done and apologize for it.
The SHIELD agents here don't like Grant because they fail to see that he was never loyal to HYDRA but to the man who had manipulated him for half his life. They don't understand what he went through and how he did what he had to, to survive and for no other reason. They think he is evil because what he has done doesn't fit nicely into their views on things.
