S3·E10 Night in Question

A bullet wound to the head lands Nick in the emergency room, where with no pulse, no heart rate, and no brain activity, he is declared dead. Fast action by Natalie and LaCroix, brings Nick back to life. While his physical wounds are healing, his mind is another matter--he has amnesia, and therefore no memories of who he is or what he is. Both Natalie and LaCroix see this as a chance to acheive their goals for Nick. Who will win this little contest, and what will be the price? Meanwhile, Nick must find the killer before he strikes again, as well as find out who he really is.
