Ok, I read a story where Buffy and Spike meet in a college class and she is immediately attracted to him but since Buffy only ever wears sweats and t-shirts to class, Spike only thinks of her as a friend. One day they both end up at a club and Spike finally sees her all dressed up and doesn't recognize her immediately as the girl from his class. I remember he sees her playing some sort of racing video game when he goes up to talk to her and that's when he finds out she's the girl from his class.
.. at some point she goes on a date with Charles Gunn and she finds out that Gunn and Spike are roommates.. it doesn't last between them and she ends up introducing Gunn to her friend Fred.
Also, i remember at some point Buffy taking a walk and seeing Spike in his driveway working on his car shirtless.. i think she trips and Spike invites her in and takes care of her ankle.. i hope i'm not confusing two different stories. |
