DS9 s3e20 “Improbable Cause”
It's a road trip with Garak and Odo (who we probably shouldn't forget about)! Will they solve the mysteries of what's happening on DS9? Or is Garak too much of a lazybones? [Episode discussion begins around 1:30. 45ish - Disco Spoiler, 2:33 - possible later DS9 spoilers, although it’s mostly Andy musing]
