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 spatially and plot wise confined.


Usually called a “bottleneck episodes” because the characters are trapped in a room together. So much of the episode is dialogue based.
Who calls them “bottleneck episodes”? That doesn’t make sense. The episode is a bottle episode because it is bottled up in one location. A bottleneck episode would mean that one episode somehow dictated the maximum speed of the series?
Why would the name suddenly be about the whole series if it’s an episode description.
It’s because episodes tend to be about getting out of the room/place/event. They’re stuck trying to get out.
lol…… no.
