I’ll go first.
Winner:
Breaking Bad, season 3 episode 10, “Fly”
Honorable mention:
Community, season 3 episode 10, “Cooperative Calligraphy”
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.
Either SG1s Grace or SGAs 38 Minutes.
I cry every time at Grace. 🩷 And forgive me, but 38 Minutes is h0t (and performance wise awesome) af. 🥰
