I actually found his relationship with Carter to be one of the more believable on the show. The Martouf stuff was just creepy. He's a man with a parasite in his head, and the only really she's attracted to him anyway is because she had a parsite in her head, and so she her those residual feelings. Was Pete really a bad match, or were the shippers just QQing because she wasn't with Jack? Carter has always been an emotional retard anyway, so it was never going to work either way.
