When ghost found out he was going to turn he broke his own jaw off to keep himself from hurting anyone, though it was painful. He knew it needed done. Once he turned, he expected everyone to abandon him, if they didn’t kill him

It's been weeks since Price declared Ghost M.I.A. earlier that day

You now walk into the bunker where you hid him, tossing a dead rabbit to him for him to eat
