Back in the classroom, Lee takes this walrus tooth or something and starts cutting(? -- I mean, there's blood or something red that happens afterwards, but Faye is remarkably chill about being sliced) her back in little lines as he tells her that there are 5 energy points along her spine. I guess this is a fresh test or something. He wipes some stuff along the cuts then wipes it with a tissue and puts the tissue in his pocket.
Diana and Adam meet in the hall and Adam tells her that he saw her dancing with Aaron and he wishes her the best. He tells her that Cassie is afraid of hurting their feelings by being around him. She agrees to talk to Cassie. When he walks away, she sheds a tear.
Lee takes the necklace from Faye and puts it around her neck, which makes the symbol around them catch fire. She's so going to get in trouble with her mother. On the dance floor, Adam, Diana and Melissa all start to swoon. Cassie sees Melissa and asks her if she wants to sit. She says she's going to the bathroom to splash some water on her face.
Faye walks towards the dance floor, stopping to unlock her locker with magic. See? That's all she needs from this magic stuff. She bumps into a girl on the floor and tells her to get out of the way, then makes her glass freeze and explode (because they are going to have actual glassware at a high school dance). Suddenly, Melissa passes out in the bathroom, hitting her head on the counter on the way down.
Cassie sees Faye and asks for the page. Faye says that she doesn't have it. Cassie calls her a bitch then walks off. So, Faye decides to make one of the table centerpieces of fake fire become real fire. She does that to all of them, until, well, everything's on fire. Diana passes out and Cassie catches her. She susses out that this is about Faye. She asks why she has solo magic and Faye says that she's borrowing hers. She got the spell from the page she stole. Adam starts swooning again and Cassie tells her that she's the one causing it. Why can't she just see that for herself? Anyway, she takes Lee aside and says that she wants to reverse the spell. She has to threaten him before he'll tell her how to do it -- set some oil on fire and put the necklace in it.
At this point, the school gym starts collapsing. Everyone's running out hysterically. Everyone's outside... except Melissa. Cassie runs back in to get her and finds her in the bathroom, but is overcome with smoke. Right before she passes out, she sees some black boots running to her.
