Seen in the crowd cheering Elyon are Aketon (Aldarn's father), Alborn and Miriadel (Elyon's Earth parents) and Elias Van Dahl (the artist from Framed).
Goof: At one point near the end of the episode when the villagers are celebrating and the girls are still in their Guardian forms, Taranee is seen with her hair in the normal way she wears it instead of her Guardian dreadlocks.
Goof: When Phobos is defeated and Caleb says: "Funny how tyrants always say that," we can see Aldarn standing behind him. But seconds later we see Vathek and Aldarn, standing on the stairs, both being unfrozen.
Goof: Blunk leads Matt through the same portal to enter the tunnels below the castle as the one used by the rebels to enter the kitchen from the Hoogong Gorge.
Cornelia: So, feel good to be the queen?
Yan Lin: What about the boy, Matt, who saw you in your Guardian form?
Will: I talked to Matt. He was a little shocked... Okay, terror-stricken after seeing the Metaworld, but he knows Elyon from school. He wants to help.
Elyon (after she has discovered that Phobos tricked her): Cornelia! Oh, Cornelia, I'm so sorry!
Cornelia: Don't get sappy on me. We have work to do.
Elyon: (to Phobos) Hello, brother!
Caleb: This is it. The final battle for Meridian has begun. You should go on ahead.
(Cornelia arches an eyebrow at Hay Lin.)
Hay Lin: Oh! I'll be in the other world if you need me.
(She leaves Cornelia and Caleb alone and they kiss.)
Phobos: No! This can't be how it ends!
Caleb: Funny how tyrants always say that.
Irma: Sorry I couldn't keep you, Mr. Huggles.
Will: Me too, Mr. Huggles!
Blunk (drooling): Blunk take Mr. Huggles!
Cornelia: No! He's a pet, not a furry snack.
Blunk: Blunk help plan battle and stay close to nice pet?
Irma: Face it dude, you're not a warrior. You are a scavenger.
Blunk (offended): Goods recycler!
Caleb (eating Silver Dragon food): We cross the Veil for the assault on the castle in twelve hours. I need all my strength.
Yan Lin (pulling the plate away from him): Save some strength for the customers.
Cornelia: I had this horrible, overpowering feeling. Elyon's in huge trouble right now!
Irma: Corny, the last emergency flash you had was that Capri pants were over.
Blunk: Boyfriend of Will! Hello again!
Matt: You're that uh, that...
Blunk (extending his slimy hand): Blunk! High-five!
Matt: I don't think so.
Blunk (shrugging): Suit self.
Will (entering the castle kitchen): Ahem, attention everyone! Phobos is about to lose his appetite. We recommend you all go home!
Blunk (biting Cedric's tail): Not just scavenger! Warrior! Grrrr!
Matt (indicating Phobos): Who is that?
Will: Unfortunately, that's the home team.
Matt: Man! I think I left my parents in the restaurant. Oh well, what's our next adventure?
Will: Our next adventure?
Blunk: Blunk visit lots!
Caleb: What do you mean, visit? You live here!
Blunk: Only part time. Earth need hero like Blunk too!
Elyon: I'll miss you!
Cornelia: No way you'll miss me! I'm inviting myself back once a week for dinner in your new castle!
Phobos: You have failed me for the last time.
