PS: I’m having a hard time categorizing these as real bottle episodes since they don’t feel cheap or “fillery” at all, but they are at least specially and plot wise confined.
Reading the Wikipedia page for Blink, I can’t see any justification whatsoever for calling it a bottle episode. I assumed from the upvotes, people knew something I didn’t, but, no, they just liked the episode so they upvoted the comment.
