Wait

If Robbie wanted Buffy, he would have just taken her on the way to the Magic Box. Besides, while this was fun it could always get more interisting.

Because of his knowlage of future episodes Robbie knew that Willow was a repressed lesbian and that Faith had a bit of a bi swing in her sex life. These two characters hated each other so Robbie was curious to see how they would handle a dose of attraction to each other along with their increasing arousal. Robbie figured that they would either break and have interesting sex, or have a sexy catfight.

This done he got up and sat between Cordy and Joyce, sending a signal to each that they should try to seduce him without attracting attention from the women on his other side.

Do Faith and Willow make love or war?

How do Cordy and Joyce try to get Robbies attention?

How does Buffy react when she comes back and finds her mom flirting with Robbie (who she and everyone else thinks is her friend Xander)?

Does the Hellmouth send a badguy after the team before any thing interisting happens?
