Spirits abound on DS9 this week, but it's not a spooky episode. Rather, Odo is haunted by his past and an unsolved case in "Necessary Evil". After that, Sisko questions the nature of a woman in red who can appear and disappear seemingly instantly in "Second Sight".
Also this week: how Odo met Justice, "Columbo" connections, and romantic Sisko.
Timestamps: "Necessary Evil": 00:45; "Second Sight": 27:53.
