 Why would Willow sleep with Parker? Wasn't she still with Oz at the time? |
Willow was really upset over Oz being attracted to Veruka, who was a fellow musical artist and could relate to him in a way that Willow couldn't. It is why she went to yell at Parker. Because she had bottled up--well, she did tell Buffy how she felt, that Veruka made her feel like a lame groupie--her feelings about Oz and frustrated and a little angry and needed someone to vent at.
