Buffy the Vampire Slayer: Season 5, Episode 3: The ReplacementWritten by Jane Espenson; Directed by James A. Contner
This is a notable episode for two reasons. First of all, it's really the last time Xander ever gets any significant character development. Beyond this, he really just falls into a groove and is steadily sidelined all the way until the end of the series. The other is that it features Xander being split into his suave half and his dorky half, the result being that we get to see two Xanders interacting. At first I couldn't work out how they did it, but then I went on to IMDB is discovered that Nicholas Brendon has an identical twin brother, Kelly Donovan, who served as a double in all the scenes requiring both Xanders to be on-screen at the same time. Either the writers were incredibly lucky or, more likely, they tailored the whole episode around this.
Anyway, a fun episode, and one that is only marred by the rather cheesy way in which dorky Xander speaks his thoughts aloud as he follows suave Xander around town.
Overall rating: 8/10.
Next time: Out of My Mind.
