Just started my post and got an idea midway through, so I put it in. Crossfire stays behind like many of his predecessors have clearly done before. Was going to have Annabelle rush Hayato out of there, but he decides to stubbornly go back to his brother, gets possessed, and with his strong will power keeps the Arancol inside him long enough for Taka to be forced to shoot the ecto bullets. OR he shoots himself. Haven't decided yet.
