Cameron's reunion with his wife and daughter. Remember, this is the first time he's ever met his daughter too.
The look on Cameron's face when he walks towards the airplane for the first time; he just looks so happy to be finally going home.
Garland Greene, who has a kill count higher than any other convict on the plane and is reputed to have worn a girl's head as a hat through three states, has a tea party while alone with a little girl, a nice talk and does nothing remotely evil to her and even waves goodbye when running/flying away.
The guy even talks about his condition with her. The fact that he can admit he's messed up is impressive in and of itself.
