Buffy/Gale.
Look. She blames me for her sister's death and I spent the last ten years trying to atone by killing every single architect of suffering that I could find (government mandated killing, alright?) ... I don't want her. I swear to you, I don't want her and I'm not flirting with you to try and make her jealous. I'm mean and grumpy but I'm not heartless.
