Okay...I was watching "TOW No One's Ready" on the new videos, and one of Rachel's sisters leaves a message--most likely her older one, since there is no name mentioned, and we know what Jill sounds like, we can presume it's big sis--that everyone hears, asking Rach if she'd slept with Donnie Mazzio, because "last night, he kept shouting, 'Two for two!'" Ross looks at her, when she says, "Do you want me to get dressed or do you wanna hear a really long story about the senior hayride?"
I'm thinking it was a senior trip while in high school, so that COULD make him a survivor. Tennant, your thoughts?
