Two of my favorite series have made me tear up:
Battlestar Galactica in the episode where Adama rescues the Colonials from New Caprica and they are all on the ships, disembarking from the shuttles and Raptors. And suddenly there is Colonel Tigh, battered, broken, looking like hammered shit. He had killed his wife earlier in the day because she had betrayed then to the enemy. He had been in prison and tortured and maimed by the Cylons. Adama say's, "You brought them back, Tigh." Tigh answers with his voice breaking full of loss, regret and remorse, "No, not all of them. Not all of them." That little dialog with Bear McCreary's awesome soundtrack rising in the background was just too much.
Last night I was watching Lost and saw the episode where Desmond and Penny finally contact each other. That moment when Penny picks up the phone after waiting on Desmond to call her on that very day for seven years was just too much also.
In my WIP one of my characters is cornered in a classroom. He has lost to much blood and knows the end in near. He can hear the SWAT Team coming up the stairs and positions himself to where he can get a couple of shots off so he won't be taken alive. He wonders what part of his life had been worth living and remembers a woman he had met and spent a weekend with. She had been married and had only wanted a fling, he had fallen in love and was pondering this when the cops come through the door and kill him.
