As the Monster Moon rises high above Degrassi’s Halloween dance, the students are in for some surprising twists and turns. During the full moon Sav turns into a monster and kills off Anya while Wesley can't believe he turned into Holly J.
With the dance in full swing, Eli tries to spend some time alone with Clare in a deserted hallway; Clare has plans of her own, though.
Zane is upset when Riley deviates from their matching costume plans.
Fiona may be beautiful, but she’s one terrible mime with a dark secret. Could it be that Drew can on the night of the dance tempt her into revealing her true nature?
- Sav: Aghhhhhh!!!
- Anya: Sav?
- Wesley: Stupid full moon. This sucks!!
- Holly J.: NOOOOOOOOOOOOOOOOOOO!!!!
- Eli: "My oh my Clare Edwards, when you told me you were going to be a zombie for the dance I didn't think you'd look so... rapturous."
- Eli: "Well hellooooo! You're a feisty little undead minx aren't you?"
- Clare: "Are you serious? I am TRYING to eat you! Don't you see this is not supposed to be sexy?"
- Eli: "Do you wanna cuddle first?" Clare: "Ugh." Eli: "C'mon, I'll let you eat my brain. It'll be HOT."
- Eli: (while Clare is biting him) "Oh. Uh. Oh yeah, Clare oh."
- Zane: "Are you serious? Just the other days when we both decided to wear matching gladiator costumes."
- Zane: "What were you thinking Riley, what?"
- Riley: "I was gonna kill you."
- Zane: "Always thinking about yourself."
- Riley: "I'm an idiot. Forgive me."
- Zane & Riley: Mime!!!!!!!!!!!
- Fiona : "This is the lamest dance ever."
- Fiona : "I went to a school in Belgium where they flew the entire student body to Transylvania for Halloween."
- Fiona : "My God, you're beautiful."
- Drew : "I know. What are you suppose to be?"
- Fiona : "A mime"
- Drew : "It's intoxicating."
- Fiona : "Sorry, darling, but I'm not one for PDA."
- Fiona : "Fiona Coyne: Man eater."
