This episode gives the explanation of why Liz got so furious with Joey for asking to do it with her in the Degrassi Junior High episode Great Expectations.
Dwayne: Sometimes I dream that I don't have it, but then I wake up and I still do, and I want to kill myself.
Joey: Don't say that!
Dwayne: It doesn't make any difference; I'm going to die anyway. You're the only one who knows... I haven't told anyone else, not even my parents. My dad would kill me if he knew.
Joey: Then you wouldn't have to do it yourself. (shocked) I'm sorry! I'm sorry! I didn't mean that...
Dwayne: (laughing) No, no... it's okay.
Spike: It's just a little kiss good-night; there's nothing wrong with that!
Liz: Well, it's easy to see why you got pregnant!
