My second Avatar: The Last Airbender amv with Avril Lavigne's "Sk8er Boi" and with the Suki/Sokka/Yue triangle. Suki is the first girl, and Yue is the girl Sokka ultimately ends up with. By the time he meets Suki again, his heart still belongs to Yue ("Sorry girl but you missed out/ Well tough luck that boy's mine now") because, like she promised, "I'll always be with you" ("I said 'See ya' later, boy'/ I'll be backstage after the show"). That's my reasoning, anyway.
I've also made an amv with the girls' roles reversed, with Suki as the girl he ends up with. Had to re-uplaod it to my other account, JillRoxyG, when Viacom deleted it. Check it out and tell me which one you like best.
