When Piper is in the parking lot of P3, she falls into a perfectly circular light shining from the light post. The light fixture was not circular and also the light shining onto the asphalt would not have a sharp defined shape.
Phoebe was going to go get Kate's jacket but her parents left without it.
When Cole transforms in the attic, one sees only his face and it stays on the same height during the entire transformation, yet in later episodes one can see that Cole's demonic form is at least a head higher than his human form.
TRIVIA: This episode features Paul Van Dyk's song Tell Me Why.
TRIVIA: This episode reveals that Prue was born in 1971 (but the month/day was not mentioned), Piper was born August 7, 1973 and Phoebe was born November 2, 1975.
In this episode, Piper claims she cannot freeze the trolls because they are moving too fast. Yet in two previous episodes she has frozen bullets in mid air. Surely she would remember this?
In this episode, Phoebe says she will not be out-stubborned by a Gemini referring to Piper. However, in the episode Pardon My Past, the family tree shows Piper's date of birth as August 7, 1973, which would make her a Leo not a Gemini.
TRIVIA: Piper mentions the Tooth Fairy in this episode. The Tooth Fairy is a fictional character in modern Western culture said to give children a small amount of money (or sometimes a gift) in exchange for a deciduous tooth when it comes out of a child's mouth.
TRIVIA: Phoebe says to Cole Turner over the telephone, "Piper likes to tease me. I like to get the mail a lot." This is a pun and refers to Alyssa's romantic life.
When Thistle turns Kate into a person again (just before she is hit with the dust) she is facing away from the girls, but when she is human she is facing towards them.
Phoebe says that at midnight the world itself becomes an "in-between" - but that is not true because of the different time zones around the world, the whole world is not experiencing midnight at the same moment.
When Phoebe levitates in the forest, in the shot where she says "Prue, a little help here!" You can see that her pants are all bunched up from the harness they used.
When Piper gets attacked by trolls in the car park of P3, she falls over and her handbag is thrown outside of the circle, but in the next shot the bag is in the circle with Piper.
Cole: Can I use the bathroom?
Phoebe: Number one, or number two?
Prue (giggling): He needs to make a poopie!
Cole: Excuse me?
Leo: They had forbidden me from ever seeing you again. But now... I don't know what you said or did, but they said you showed great courage and great faith. Enough to make them reconsider.
Phoebe: Does that mean you guys could get married now? (Prue gives her a bump) What? I wanna know.
Leo: Not yet. It means they're giving us a chance to prove we can make it work.
Phoebe: What do you mean, like probation?
Phoebe (to Piper): You are being a big, big, big, extra, extra, double big jerk right now!
Cole: Course we could always have dinner instead.
Phoebe: Are you asking me out, counsellor?
Piper (about the Elders): Why are they doing this to us? It's like destroying lives is how they amuse themselves.
Prue: Piper, watch what you say.
Piper: Why? What are they gonna do to me? They couldn't hurt me more than they already have.
(Talking about falling down the stairs)
Cole: You two seem different.
Cole: I mean, I thought maybe you were, I don't know drunk or something before. Now you seem...
Prue: Sober. (Cole raises his eyebrows) (Prue hesitantly and slowly) Stairs can be... sobering.
Phoebe: Right, ok, um, I'm really sorry about our plans there, Cole. I really am.
Cole: No worries. I'll keep trying.
Phoebe (Mocking sarcastically): Stairs can be sobering?!
Prue: Ok, what was I supposed to say? That some unknown demon came in to steal our magic book and little trolls came and pushed us down the stairs?
Phoebe (Sarcastic): Right.
Piper: What are they doing?
Prue: Looks like they're trying to start a fire, although I don't really think that it's for roasting marshmallows.
Piper: First troll I see is in really big trouble.
Prue (talking about Piper): She said that she was coming, right?
Phoebe: What, did you think I just made that part up?
Phoebe (to Prue): That's why you're the older sister, you are always thinking.
Phoebe: Did you not look at those drawings?
Piper: They're cute, yes.
Phoebe: Cute? Cute? We all had the same invisible fairy friend, Piper. That is proof that fairies exist.
Piper: Or... it proves that one of us had a really fertile imagination and the other two were really good copycats.
Phoebe: You really gotta lay off the rhyming, Prue.
Piper: (calling) Phoebe, phone. (Phoebe comes and takes the phone.) It's your little lawyer boyfriend.
Phoebe: So there. And he is not my boyfriend.
Phoebe (into the phone): Hello?
Cole: Who's not your boyfriend?
Phoebe: Um... the mailman. Sometimes Piper likes to tease me because I like to get the mail...a lot.
(on the phone)
Phoebe: Hi. Cole. What are you doing in the office at 2 in the morning?
Cole: What are you doing calling my office at 2 in the morning?
Phoebe: I was just gonna leave you a message. Save you the trouble of having to talk to me.
Cole: Why would I ever not wanna talk to you?
Phoebe: I... I don't know, you know. Just in case you thought I was a drunk or a lunatic or a drunk lunatic.
Cole: I think I'm gonna go with "mystery". One I'm looking forward to figuring out.
Phoebe: Okay. I'm gonna go then and be mysterious.
Cole: I'll call you.
Phoebe: I will answer.
Phoebe: Prue, that was a very, very big troll.
Prue: That's not a troll, it was a demon!
Prue: I want to see the fairy.
Phoebe (about the little girl): I gotta go to the car and get her jacket. (she walks over to the key hook.) Uh, keys?
Phoebe: You know, silver shiny things that go jingle jingle.
Cole: Do you think I could use your rest room?
Phoebe (rolling her eyes): Number 1 or number 2?
Prue (giggling): He has to go tootie.
Prue: Do you think trolls know about doorbells?
Prue (right after the trolls ran through the fire and burst into flames): Oh, now that is just the way I like my trolls, medium well.
Piper: Fairy dust?
Piper: Okay, great, so you can go home now and reverse it, Tinkerbell.
(Prue and Phoebe are on stage singing the song If You're Happy And You Know It at P3 when Piper walks in) Piper: What the hell is going on? Abby: You think this is bad? You should've been here for Frere Jacques.
Kate (about Thistle): The trolls are gonna kill her unless her parents hand over the kingdom.
Phoebe (to Prue): It's a miniature coup d'état.
Piper: And after what they did to Leo, I'm not really all that motivated to go dig up demons for them.
Phoebe (to Piper): I don't wanna be out-stubborned by a Gemini.
(Piper and Phoebe are arguing about what attacked Kate)
Prue (stepping in between them): Okay. So, it's kinda late, and, ummm, we're all a little bit tired so how about we finish this up tomorrow?
Phoebe (to Piper): Now look what you did, you went and turned Prue into the middle child.
Piper: Why are you being so stubborn about this?
Phoebe: Because I'm a Scorpio, what's your excuse?
Prue (on the phone): Hey, uh, it's me.
Phoebe: It's amazing how much stress you can project with so few words, Prue.
Piper: The tooth fairy is going to come and harass us all for not flossing?
Piper: Come on, Phoebe, trolls and fairies? You don't believe that stuff.
Phoebe: Sure, why not?
Piper: Well, maybe it's time we tell her about Santa...
Piper: The Powers That Be haven't done anything but ruin my life so, therefore, I'm not gonna do anything for them anymore, okay? I'm going now. Excuse me, I'm going now.
(Piper pushes past them and leaves)
Prue (under her breath): Ow.
Phoebe (sighing): I think she's on strike.
Piper: Okay, what ass-backward spell did you guys cast?
Phoebe: Are you worried?
Prue: When are you going to learn? I am always worried.
Piper: You better run while you can, you little rodents. I bet you guys think this is real funny, don't you?Haven't you taken enough from me? You have to send trolls to kick me while I'm down? I had a nice normal life once. And you took that from me. You took my boyfriend, you took my life, the least you could do is leave me my freaking car keys!
