The fall of Barrier City 42, New York City. You are dead inside if you don't wear the same expression as the Deep Eyes after listening to the desperate screams and death cries of the people in the shuttle and rooftop scene. It is Nightmare Fuel that will shake you every time you watch.
The whole scene where the Deep Eyes perish.
Including Neil and Jane's shocked faces when Neil gets killed by a phantom and then when Jane realizes she can't escape either. Considering how Jane always picked on Neil, it was especially touching how she reacted when he died. When she realized she was trapped, she made sure her body fell next to him in death. Pass the tissue.
And the Big "NO!" scene where Grey screams out Ryan's name just after he dies.
Kind of hard not to feel something when Aki is mourning over the loss of the Deep Eyes and New York City.
When Grey sacrifices himself.
Upon their arrival at the old battlefield, Ryan says softly, "My father's down there somewhere." Becomes hard to look at that field and not start thinking that each of those suits was once a father, a husband, a brother, a son...
