That’s right. I remember the elevator scene as well.
My understanding is the networks don’t get official extended cuts from the studio (except maybe in the case of 1 & 2 since there has now been a retail release). They only get the pieces if they want to cobble something together themselves.
It’s why there is slight differences between ABC/Freeform edits and Syfy/USA/E! versions.
Do you know if someone has preserved the ABC broadcasts? I remember them doing a better job at putting together the extended Yule Ball ask out sequence. From my memory, it played out this way.
