The episode credited Zoe Bell as a guest star tonight, but I didn't see her. Isn't this the same Zoe from Quentin Tarantino's 'Deathproof'? I remember hearing she was going to be on the show, but i never saw her tonight.

Did I miss something?

I think she is playing the woman on the other side of the phone.

thats what i heard as well

She was the girl on the radio (Rachel?) that Dan was talking to to start his experiment. I really hope we get to physically see her (and Fisher Stevens, the other radio voice) on the show at some point.
