15 Best Teen Wolf Episodes
9. Memory Lost (Season 6, Episode 1)
As noted, the first half of season six is a revelation, and it starts in particularly awesome fashion. As their school lives come to an end, Scott and Stiles grapple with the idea that Beacon Hills doesn't need them anymore. That is until the Ghost Riders come to town, at least, and start erasing the locals from existence.
Though this sounds like a standard episode set-up, things take a major twist when one of the Riders' targets turns out to be Stiles, who is erased from existence as he declares his love for Lydia and begs her not to forget him.
The episode ends with everyone returning to school the next day, unaware that they're missing the most important person in their lives. Memory Lost fits so much narrative into just forty minutes, it's remarkable it didn't come out a jumbled-up mess. Instead, it's one of the best episodes of the show.
