Quote villyforever55: I didn't get any real concern for Jack from Adam, especially not after watching him make a deal with Victor while standing over Jack's bleeding body. And certainly not when he goes to see Jack and is still hoping Jack will cover for him. No, not buying it at all; Adam is only worried about Adam.
He made the deal with Victor when he still thought it was Marco, following through with the plan. He didn't figure out the blood was real until Victor left, and only seconds later he discovered it was actually Jack, when Marco appeared.
