Meme lemming is a lemming

So there's a meme going around: Name a character I've written, and I'll tell you the three things I think are essential to writing that character.

friendshipper changed the meme a little to say: Give me a character relationship -- i.e. name two characters from a show/book/movie who have some kind of relationship in canon (friendship, coworkers, enemies, sexual relationship, blood relationship, whatever) -- and I'll tell you three things I believe about the relationship between those characters.

Either one of these works for me. :) Ask me stuff, y'all. Let me pontificate.
