Remus/Tonks. I read the books after seeing the first four movies and at the time, Remus made no impression on me. Then reading the third book, I was completely in love with the rumpled werewolf. And Tonks was awesome right away. When it was revealed she was in love with Remus, my response was, "Of course. Who wouldn't be?"

And I had to respect why he didn't persue her. He thought she deserved better. Which is always the formula for the truly great loves. She knew there wasn't any better. Even when he went barmy in Deathly Hallows, I hated him for it but understood. Also, being two of three favorite characters in the books, I was fine with their fate as it was the last book. Last in the series, you can kill everyone off, I'm cool. If your curious, Serius was my other fave and yes, I have issues he died when he did. (The only thing I truly disliked about the last book had nothing to do with pairings, btw.)

I would have loved for them to live and raise Teddy but at least they went together.
