Buffy AU: Faith shows up uninvited at The Prom night to try and make amends with Buffy, but then she saw Angel walking in and the way Buffy looked at him. And thats when she finally understood that it wasn’t where she belonged. Not with Her. Ever. - “and i saw what it was; i was wrong.”
When I was younger and watching Buffy for the first time, I used to think that Joyce and Giles were going to end up together. Giles was a more present father figure for Buffy during the show than her actual father was, and it made sense to me to assume that he would one day be her step dad.
