6. Party Guessed (Season 2, Episode 9)
In Party Guessed, things take a series of sinister turns at Lydia's birthday party. Manipulated by visions of Peter Hale, Lydia hosts a massive party, with Scott, Stiles, Allison and Jackson in attendance, and spikes the drinks with wolfbane, causing everyone to start hallucinating.
Scott imagines Allison with Jackson; Stiles sees his dad blaming him for his mother's death; Allison faces off with herself; and Jackson is confronted by his "real" parents.
Amongst this surreal chaos, Jackson tries to keep Isaac, Erica and Boyd under control during the full moon, and Argent is forced to help his wife kill herself before she becomes a werewolf. It's a lot to pack into forty minutes, but Party Guessed balances every aspect of the story with startling precision, creating a moving, scary and dark narrative.
Also, it ends with Peter being risen from the dead, an event that will shape the next two seasons in some pretty major ways.
