Looking for a line with animosity and drama! Something in X-Men, Avatar: The Last Airbender, Star Wars or maybe Harry Potter. Check the journal for characters and pairings, but really, I'm looking for an unconventional pairing with drama and angst. Offer a few characters you play, what you're looking for, and we can brainstorm something! Some favorites: Jet or Katara/Zuko, Shadowcat/Pyro, James/Severus, Sith/Jedi.
ETA: Inception? Arthur/Ariadne?
