So, Melissa is in Nick's bed and she's got that demon in her ear and it makes her NOT a morning person. She pushes Nick across the room when he tries to kiss her. Cassie lies to her grandmother that she doesn't know who Heather was. Grams tells her that her mom's friends all went through a lot together. Um, understate much? Cassie wants to confide in her grandmother but Diana tells her that something in her Book of Shadows talks about their parents' Circle being punished by elders and she imagines that Cassie's grandmother was a part of that group.
At school, Diana tells Faye that their parents are dating. Heh. Melissa acts progressively crazier as the day goes on. Finally, she's writhing on the floor in pain. Luckily, she's the only person in the hall and Nick is the person who finds her. Despite how ridiculous that is, the actress playing Melissa is pretty stellar. She snaps into crazy calm demon and tells Nick that she's fine but needs him to help her find her family's Book of Shadows, which she hears is in the woods. Nick likes the ideas of just doing magic with her in the forest. She takes him to the woods and makes the poor guy dig into the dirt forever, until he finds a satchel. They take the satchel to the abandoned house and Melissa insists that they not open it until everyone is there. She's acting super spooky and kind of comes on to Faye, which of course we've all been waiting to happen anyway.
Dawn and Charlie have dinner together. Ew. Diana makes dinner for Adam and it's gross but they have a nice time together. So nice that clothes come off. Meanwhile, Melissa has almost blown her demon cover by screaming at everyone to wait to open the satchel. Before it can be gotten too busy with, they've called and interrupted Diana and Adam. When they get there, Nick knocks Melissa out. They tie her up and she has some NASTY talk to throw around.
Dawn and Charlie start to chant together and it looks at first as if something about to happen, but it doesn't. Dawn says that they waited too long to use their crystal now everything is screwed. Not as screwed as our young witches. First of all, something's moving in that satchel. Second of all, Melissa frees herself and holds scissors to Nick's throat and orders everyone else around. Meanwhile, Cassie has run home and told her grandmother that she knows she's a witch and needs her help. Melissa tells everyone to chant at the suitcase and it starts to open, but Grandma comes in and stops everything. Then, she performs an exorcism -- well, she's about to when she realizes that Melissa is no longer possessed. Now, the demon's in Nick. He runs out and they burn the suitcase, which is full of demon snakes.
Nick calls and says that they have to deliver the suitcase to him or he's going to burn down The Boathouse, where Adam's passed out hot dad is. He sits down beside Dawn and reminds her that she summoned him years ago! That bitch! He says he wants the Circle. They walk out and she calls Charlie and lets him hear what's going on. They are in a dry dock area when Charlie knocks Nick/Demon out. Dawn says that they have to drown the demon and Nick will be going along with it. So, Nick comes to right as Charlie's ducking his head under water and then it's demon-y but still Nick and all rather upsetting. Ultimately, it looks like the demon and Nick are drowned. Dawn and Charlie scram before Cassie and her grandmother find him lying by the water.
Melissa doesn't remember anything about her possession. Faye tells her that she's really glad that she's OK. They get a call from someone and Faye is stunned. Dawn tells Charlie that they did the right thing but he doesn't agree. Ya'll, Nick is dead? Cassie asks her grandmother what happened the night of the fire, but she says that she doesn't know. I'm a little bit surprised that the people on this show aren't as upset about Nick's death as I am. Does this mean the Circle won't be as strong? We see Faye comforting Melissa. And, we see Cassie looking out her window to where she would normally see a hot shirtless Nick.
It's our usual beginning, with Melissa and Nick waking together. Nick has to shake Melissa and she says that she has a really bad headache. Yeah, a demon headache. Nick tries to kiss her and she seriously like pushes him across the room. That is a really lame demon- - if I'd been trapped in ole' catatonic Heather Barnes's body for 16 years, I'd be super ready to get it on with Nick. PRIORITIES, Demon. You can take over the world in a few minutes. Melissa apologizes and says that she doesn't feel well. She lies back down and you can see the demon slithering (hence the title of this episode) under her back skin.
Cassie's making her breakfast as Grandma is arranging flowers. She says that she can't believe that Cassie had to witness Heather's accident. She mentions that she knew Cassie's mother and had been housebound for years. Oh yeah? She asks Cassie what she had been doing and Cassie says she was hanging out with the girls. Grandma says she's happy that Cassie has made friends with them and that it makes sense because their parents were all good friends. She says that her mother and her friends went through a lot of tragedy together. She says that she'd like to have dinner with Cassie that evening and tells her that she can tell her anything. Cassie's mute.
At school, Melissa is all jittery in the hall. Girl is WORKING that demon. She bumps into Dawn and is like, "WATCH IT!" and then backtracks when she realizes she just screamed at the Principal. Awesome. Dawn tells her to watch where she's going and Melissa twitches down the hall. Cassie tells Diana that she wants to tell her grandmother about the Circle stuff but Diana says they'll get their powers stripped by the Elders (their parents). Cassie says she doesn't like lying to her grandmother. Diana is afraid that exposing themselves means they will never find out about what happened on the boat.
Charlie is waiting for Dawn in her office. She says that they're not equipped to help their children yet. Charlie says it's a blood moon tonight. Hmm. Dawn says they should start talking by phone again. Outside the office, Phoebe tells Diana that her dad is there and she's probably getting expelled. Heh. Diana tells her that, in fact, their parents are dating. That's what I like about Diana. It almost feels like she knows everything there is to know already and is like super evil or something. Faye is not happy with this news. Here comes Melissa. She opens her locker and is freaked out by the bell ringing. She can't concentrate and then she gets a demon jolt or something and starts writhing on the ground. Nick sees her and asks her if she's OK. Then, she gets all normal and acts like nothing happened. She tells him that she found her family's Book of Shadows. Well, she found her mom's diary talking about burying the book in the forest. They decide it will be a secret between them. A Secret Line.
