Taking its title from Greek mythology, this quiet, character-based Odo episode uses a long lost Changeling as a figurative mirror for Odo to look into and reflect upon himself. (In a non-figurative sense, the new Changeling is a real jerk). As Odo begins soul-searching, he once again starts to waffle about what he really wants, which is really the point of the story. (It is a bit odd to see him go on about "Changelings" getting no respect, when he's always been given respect by both sets of humanoids he's worked for on the station; but it is true that no one has cared as much as him about other Changelings. Probably because of how the Founders act!)

Hertzler) is fine as Odo's new pal (using a completely different voice than his usual General Martok gravel), but this one is really carried by Auberjonois, who teams up with Echevarria to point Odo in the direction he needs to be to finish the series. In fact, Odo could really use a counselor here, and yet it's one of the few episodes the season without Ezri!
