Stefan was out for justice on The Vampire Diaries Season 6 Episode 3. After Enzo snapped his girlfriend's neck at the end of last week's episode, Stefan was ready for payback. He finally told off his crappy boss and left for Mystic Falls.
After reuniting with Elena, Stefan was shocked to notice how she talked about mourning Bonnie, but not Damon. Since Stefan has been so out of the loop he wasn't aware of Alaric's compulsion experiment. Caroline on the other hand, is not a huge fan of Elena having her memories wiped out. She reminds Elena that not everyone is able to just forget. Of course, there is deeper meaning when she says it but Elena doesn't know that.
Once again, everything revolves around not mentioning Damon to Elena and keeping her away from the edge. Well it seems to work because she wants to throw a party at the swimming hole to get her friends back together. While Elena pounds Jello shots, Caroline is moody, Tyler is working on his rage, and Matt is trying to protect the town.
Poor Matt still hadn't realized that there were vampire hunters on the Mystic Falls community safety squad. This becomes apparent when his drunk friend tries to shoot Stefan and Enzo in the woods but Enzo takes him out. Stefan is about to shoot Enzo anyway, but Caroline quickly saves him. He gets his revenge later in the episode when he helps Tripp Fell sedate Enzo.
Back in 1994, Bonnie and Damon finally confirm they are not alone when they meet Kai. Bonnie also gets her magic back.
Lastly we realize that compulsion wears off once you are back in Mystic Falls, meaning Jeremy's new girl remembers that Elena bit her.
