They can talk about anything Jack wants, later. They have a lot they need to talk about beyond that, like him apologizing for all the shit he put Jack through, all the things they both said in the interrogation room, and -- well, here, Jack. Have a stab of apology now as he takes a couple of steps forward and levels a kick at Jack's knees, trying to bring him down. Just because he needs Jack to get away doesn't mean he can make it easy on him. He has to be able to say he tried. Jack has to be able to say that he did, if anyone in the Eye takes issue with any part of this, later.
