As would be expected, the reappearance of Nick creates a lot of conversation. Melissa is eager to look at the development as a positive thing, but everyone reminds her that he's probably just a demon in a Nick shell at this point.

Cassie has to go to the high school alone to look for Adam's family's crystal. Security there is really weak. She's performing this blood trick thing when she sees a vision of her mother calling out for Elizabeth. Charlie gives Diana a necklace that belonged to her mother. But, enough with all that fluff -- it's prom night!

Nick shows up at 7 Briar Hill and tells Melissa that he wants the crystals -- he says he's dying. Then, Adam gets there and Nick throws Melissa to the ground and runs away. Diana sees Grant at the coffee shop and asks him to meet her at her house later. Charles gets this weird phone call (with some magic help from John) that replays the fire in the kitchen scene that happened to Amelia. He's being haunted.

Diana and Cassie do the blood spell thing and see their mothers in high school. They were all still in high school with babies? They see an argument that their mothers had -- Elizabeth blamed Amelia for bringing John in the Circle.

Adam and Melissa share a dance in the hallway of prom. On the floor, Jake and Faye have a slow dance. Jake blames himself for Nick's death but Faye tries to convince him that he wasn't at fault.

Diana and Cassie see another scene, this one with Amelia talking to Adam's grandfather. It becomes clear that John had manipulated all of them in order to create his own Circle. He made sure that all of their parents conceived when they did. When they come out of the vision, Diana's all judgmental about how Cassie is to blame for John being in their lives.

Meanwhile, Nick had busted into prom by killing a security guard. He finds the crystal and almost kills Adam in the process. Diana goes home to find Charlie huddled in the corner of the kitchen. While he's mumbling, it becomes clear to her that he killed Amelia. She wanders onto the street while it's raining and is comforted by Grant, just as John was about to pounce. Not sure what he had in mind.

The Circle follows Nick to some junkyard. He's there to give the crystal to Eben, though Eben is more interested in the demon that's propping up Nick's bones. Cassie uses magic to knock the crystal away from Nick's hand, but then Eben tosses her over several cars. John shows up to stand off against Eben, while Nick struggles with Jake over the crystal. Nick is about to choke Jake to death when poor Melissa comes along and stabs him in the back. I think he's really dead this time. John shows up and says that Eben is gone... and he has taken FAYE!
