Of course, it's possible that he's already left, and just left his shorts. Or she wasn't in when they started and didn't notice them when she came in (seems...rather unlikely, even if they'd already finished the fun and had fallen asleep or sommat). Still, at first blush, it seems most likely that a fella's come into the room while Sara was having her dream. And, since Lisa's neither a jerkass nor an idiot, having made that agreement just that morning...
That's a good point.
Also, now I think of it, regarding the "Lisa got smashed" explanation, Lisa, like several but not all of her friends back in high school, doesn't drink. And in her case, as I think T stated once (can't recall when), it's because she, like Katy-Ann in "Communion," has been afraid of what negative aspects of herself might come out under the influence. That of course doesn't mean she'll never drink, ever, but it does make it that less likely she'd get blitzed, even during the rough night she's had.
