Agent Kyle Brody
Leslie St. Claire
When the smoke alarm on the ceiling starts bleeping, Piper asks Leo to turn it off, to which he replies he'll go fetch a ladder. Why use a ladder when he can levitate?
TRIVIA: Joel Swetow previously appeared as Avatar Alpha in the season 5 episodes "Sam I Am" and "Centennial Charmed".
TRIVIA: Piper previously transformed into a beast under the full moon in the episode "The Wendigo".
A blue moon is not actually blue. It is a full moon that occurs in a month that has already had a full moon. Paige says that she read in the "Book of Shadows" that the occurrence of two blue moons in a single year happens only once every 50 years; but according to science.nasa.gov, this phenomenon happens about once every 25 years.
TRIVIA: The ice cream Paige is eating is "Ben & Jerry's Phish Food" which in real life is known as Rose McGowan's favorite.
When Phoebe is talking to Leslie and she starts to read the newspaper she is supposedly reading from horoscopes. However she is looking at the bottom left and by the view of the newspaper it's clear that the horoscopes start on the top right.
TRIVIA: This marks the sixth and final appearance of Nick Lachey as Leslie St. Claire.
Paige orbs out as soon as Piper bursts into the dining room, startling Paige causing the orbs. She also gets startled and orbs when Brody arrives and spots Paige at his place. Yet when Piper blows up the chandelier, Paige flinches but doesn't orb - wouldn't that cause her to be jumpy and startled, and then orb?
Why would the Elders think Leo attacked the new whitelighter - the guy was clawed (and presumably bitten). How would that possibly tie to Leo?
It's been shown in the past the Elders can listen in on conversations when they're not present, so is it really a good idea for the sisters to be discussing Leo's situation out loud in the kitchen?
Considering they want to make the Avatars the "new and most powerful threat ever" they seem actually far weaker than their appearance in season five. Back then, the Avatars showed they have complete control over time, surely instead of obviously exposing themselves to the Charmed Ones (and bringing Piper even closer to Leo) they could have just rewind time a few minutes earlier and kill the demon before he could speak to them. In fact, why even keep him alive at all after what he did?
When Paige grabs the ice-cream it still has the cover on and there's no sign of a spoon and Phoebe starts talking to her about personal gain. In the next frame, while Phoebe is finishing her sentence, we see a close-up on Paige and the cover is off and she has a spoon filled with ice-cream. There wasn't enough time (less than a second) for her to open the cover and pick up the spoon.
(The Possessor Demon shimmers in the kitchen)
Leo: Who're you?
Possessor Demon: Actually, I'm about to be you. (possesses Leo)
Phoebe: Any idea what this meeting's all about?
Paige: Oh, probably something to do with the kids
Phoebe: Why, did something happen?
Paige: Oh, I'm sure they've gotten kidnapped by the latest demon or something.
Paige: Well, he's fine now, though. You know, we dis-possessed him.
Agent Brody: Wait - you did what?
Paige: Well, we got rid of the demon. We get possessed all the time - it's no big deal.
Piper (after burning the second batch of muffins): Great. Now not only am I exhausted, but I'm starving.
Phoebe: Ooh. I see your "exhausted" and your "starving" and I raise you "bloated".
Piper (about a new whitelighter): Look, we have enough people orbing in and out of here on a daily basis; we don't need another. (She blows up the toaster)
Leo (looks at the toaster): Got it. (He orbs out)
Phoebe (sadly): That was a great toaster.
Piper: Paige try and orb one of these crystals away.
Paige orbs the crystal through a window and Piper stares at her.
Paige: Blue moon?
Phoebe: So when can we talk?
Leslie: I don't know, maybe, tonight at dinner.
Phoebe: Oh I can't do it tonight, but I can do breakfast tomorrow and then maybe dinner and then maybe breakfast again.
Leslie: I'll hold you to it.
Phoebe(to a whitelighter): You know for a whitelighter you are very wimpy.
Phoebe (about Piper's burnt muffins): Oh that is so sad.
Paige: Eh, eh, eh, no weeping. You promised.
Odin: No. What I saw was what I never would've imagined. The Charmed Ones turning into demons.
Phoebe: No, that wasn't demonic. That was, you know, that time of the month.
Paige: No! It was a Blue Moon.
Piper (to the Avatars about Leo): Whoever you are - stay away from my husband!
Phoebe: So what time's your flight?
Leslie: Noon. So you ready to come back?
Phoebe: More than you'll know. Thanks to you.
Leslie: Me? I didn't do anything, I just kept the seat warm for you.
Phoebe: You did more than that, and you know it. When I first met you, I was totally lost. That's why I needed to get away from all of this, you know? I couldn't give advice, especially not about love, and I realized that, I was just afraid, but I'm not afraid anymore. (They kiss) Thank you.
Leslie: You're welcome. I guess it just wasn't meant to be, you and me?
Phoebe: Maybe not right now.
They hug for one last time.
Leslie: See ya.
Phoebe: See ya.
Paige: Hey, maybe he's pulling away from you because hmmm, maybe he's... I dunno...leaving.
The sisters wake up after turning into the monsters.
Paige: What happened?
Odin: You attacked us.
Phoebe: Oh really, then how come I'm the one with the headache?
Odin: We were forced to protect ourselves.
Paige (to Phoebe): You get so emotional when you're PMSing.
Phoebe: Yeah, and you get mean.
Paige: I do not get mean, I'm above it all, nothing happens to me.
Piper walks in.
Piper: Alrighty then!
Paige orbs out then back in.
Phoebe: Oh right, nothing happens to you, you're above it all.
Paige: Fine, I get a little jumpy.
Piper: And I get a little pissy, so watch it.
Paige & Phoebe: We know.
Paige: We're demons?
Piper: No, Paige, we are not demons.
Phoebe: We're monsters.
Paige: Okay, I knew we were a little testy this time of the month, but this is just crazy!
Phoebe: Oh that was just the blue moon. It won't happen for another 50 years.
Piper: Yeah, and by that time we'll just be a menace to our rest home. So I think you're safe.
Leo: Piper, you can't blow up a whitelighter.
Phoebe: Why not? She blows you up all the time.
Leo: What's going on with you guys?
Piper: Witches with PMS. Look out.
