Yes. I knew them, in this life. Circumstances had just changed for the experiment.

Kendra was the Slayer who was called after Buffy's first death. She, however, was eventually killed by Drusilla. Larry was a football player with an unusual fondness for tormenting Xander. He died on Graduation Day. Oz was a werewolf who dated Willow for a while before he left Sunnydale. Tara is Willow's girlfriend.
