Given where and when Zelenka grew up, somebody disappearing and not being mentioned again isn't too big of a stretch. It just depends if you think it happened in 1968 or after.

I have yet to watch all of it. Rodney going to Sam's quarters and the fruit basket thing was the last straw. My humiliation squick was hit so hard and so often to that point that I'd already skipped about half of it. I decided the better part of valor was to read people's reactions and be forewarned before trying again.
