Do you think one of these 3 should have died? Would it be emotional? Or do you think one of these 3 will die in TF5? I can see Hound dying in TF6. Maybe Crosshairs will die in TF5? He could save Optimus because he finally respects him. He could say "damn, your leadership brainwashed me haha!" then drift could reply "well, he is Optimus Prime". It's just a thought, plus it develops Crosshairs character.
