Tear Jerker: True Blood
Lafayette's panicked reaction to former Detective Andy's enraged accusations that he killed Miss Jeanette. Terry's kind, calm consoling towards Lafayette also count for this as well.
Eric: Mr. Unflappable Stoic, breaking down in tears and begging Godric not to commit suicide.
"A human with me at the end, and human tears! Even after two thousand years, I can still be surprised. In this, I see God." If it wasn't Eric breaking down and weeping blood, it was Godric's total calm acceptance and joy combined with Sookie weeping that'll bring a lump to your throat.
