Gosh, there are LODAS for me.
Cordelia becoming part demon to keep the visions.
Doyle sacrificing himself so that Angel didn't have to.
Connor allowing Angel to know that he knew the vampire was his father.
Gunn staying the in hell dimension so that they could get Lindsey out.
Illyria pretending to be Fred so that her parents wouldn't be sad.
Xander buying Cordy's Prom dress.
Willow and Xander giving up their Christmas vacation to help Angel, even though both of them have issues.
Xander going to Willow at Kingman's Bluff, and telling her, if she wanted to end the world, she had to start with him.
Spike going back to rescue Xander when Caleb puts his eye out...ok, so that one's really just for me, lol.
And, of course, the obvious ones, Buffy sacrificing herself or Dawn, Spike allowing Glory to torture him because he wouldn't give up Dawn.
