This is awesome. I really enjoyed spending my day going through all 5 posts.

What I missed in the list though was the time Charles talks about his self doubt, after his and Moira's son is killed, and then he starts crying because Erik bought tickets to his lecture at Madison Square Garden. And then a mind-wiped Erik hugs him, despite "hardly knowing him".

That's the only X-Men comic I have read, so I wonder how many other slashy moments didn't make it in your list becase there were just so many!
