I'm going with "out of it due to heavy pain killers" too - because that was in the flashback.
I've been re-watching (as I was considering in my post the other day) and realizing just how much foreshadowing there really is in this series! The example I happened to notice Wednesday was back in season 1. - Tess is the one to tell them all that William is "gay, or at least bi" and later in the episode Randall and Beth are talking about trying to get to know Jessie, and one of them says it's good practice for when the girls start bringing home boyfriends, and the other says "or girlfriends" and they talk about that a little. I just think there are a lot of little things like that - stuff we wouldn't think anything of at the time that connects later.
Maybe it's the writers's consolation prize to us for making the series so short
- we can all keep analyzing it by watching it over and over.
