Buffy 5.03 - The Replacement
First aired: 10/10/2000
The demon Toth fires a strange weapon at the Slayer, but Xander jumps in front of Buffy at the last moment. The blast sends him sprawling into a mound of debris, but after chasing off the demon the Scoobies collect Xander who seems to be dazed but alright, and walk him home.
A few hours later, a second, very confused Xander crawls out of the debris and makes his way towards home.
