When the Brotherhood of Evil detect Kole speaking on the transmitter, her location shown on the map is just north of the Caspian Sea. That spot is too far south to have the Arctic landscape and Northern Lights featuring so prominently.
When Gnarrk finally frees Kole, the spanner he is holding is much larger than it was previously.
When Dr. Light monologues at the start of the episode, Robin responds to him right after the Titans arrive. How could he have heard what Dr. Light was saying if the team was miles away from him?
Dr. Light's suit resembles that of Batman Beyond villain Shriek, who used sound rather than light as a weapon.
After his suit's powers are amplified by the Northern Lights and he is able to hold his own against the Titans, Dr. Light is so confident that he'll win, he proclaims that "At long last, I will finally deafeat the Teen Titans." Light has every reason to say this, he first battled and was defeated by the Titans in episode 6: "Nevermore," and since then he hasn't gotten any closer to being able to beat them, unlike other villains like say, Slade or even Mumbo. Battles with villains like those two usually take the most part of an episode, whereas battles with him only last a few seconds or so and are usually ended abruptly by Raven. The point is that even though he appeared fifty-two episodes ago, he has battled the Teen Titans on a least three occasions, and has constantly upgraded his suit, he hasn't gotten any closer to beating them until this episode.
When they all first meet Gnarrk and Kole, and Kole says something about dinner, Starfire looks abnormally skinny for herself.
Raven seemed to have forgotten how to use her powers in this episode. When Dr. Light puts up the wall of light or whatever, she could have easily taken them through it. Starfire and her could have taken them above it, for that matter. Also, when they all fall inot the tarpit, why doesn't Raven just pull them out with telekinesis? She lets herself be dragged in. She also could have pulled the things that held Kole in place away with telekinesis.
At first Gnarrk couldn't move the things holding Kole and needed the wrench. He starts to open one, then loses the wrench. He is then able to pull away all three -- even the two he hadn't loosened up yet.
When Cyborg had talked to Gnarrk, he repaired himself and tightened a bolt counter-clockwise instead of clockwise.
When the ice cracks, why doesn't Starfire simply fly rather than bounce/fall down with the rest of the Titans? For that matter, why didn't Raven or Beast Boy? And why did Beast Boy turn himself into a penguin? Penguins can't fly.
When the Titans get out of the water that they fall in when they go through the ice and throw the snow clothes into a pile, Beast Boy's gloves are in the pile of clothes, yet he is still wearing them.
When Kole got captured, she went from normal to a crystal to normal again.
Kole: So, what brings you down here?
Beast Boy: Uh, gravity!
Beast Boy: That was close.
(Ice cracks beneath them)
Raven: You had to say something.
Cyborg: I can't believe a little girl like you is so tough.
Kole: What, you think only big guys can be strong?
(Raven & Starfire glare)
Cyborg: Uh, no.
Kole: We can help, but do you have time for dinner first? Just picked a lovely bunch of cocopolinos.
Cyborg: (To his stomach, which is growling) The girl said "dinner."
Starfire: It would be rude of us not to partake in the bounty of this land.
Beast Boy: As long as it's vegetarian, I'm in!
Kole: Starfire, shoot me.
Kole: I need you to shoot your starbolts through me.
Starfire: I do not wish to hurt you.
Kole: You couldn't if you tried.
Cyborg: (After being saved from the tar pit) Aw, man, I got goo in my gears.
(After Beast Boy talked to the dinosaurs)
Robin: What did they say?
Beast Boy: Well, they want to eat us.
Starfire: (About the dinosaurs) Beast Boy, perhaps you can communicate with them.
Beast Boy: (To dinosaurs) Uh, nice dinos?
Raven: Hey, genius, I think she means try it in their language.
Robin: Your machine can't take any more.
Dr. Light: Illuminating theory, but I have the definite advantage.
(Machine begins to shut down)
Dr. Light: Or not.
Raven: Dr. Light, why do you even keep trying?
Dr. Light: Soon, I'll have all the power of the Northern Lights at my fingertips. And up here at the Arctic Circle, no one will ever come to stop me.
Robin: Wanna bet?
Kole: For a supervillain, you're kind of a weakling, huh?
Dr. Light: Yeah, well, for a little girl, you sure are heavy.
Kole: Sorry, Gnarkk isn't very good with people from the upper world.
Beast Boy: Neither is Raven.
(Raven glares at Beast Boy, eyes glowing; Beast Boy laughs weakly)
(After the Titans defeat Dr. Light)
Raven: You're a sad little man, aren't you?
Dr. Light: Uh-huh. (Cries and whimpers)
Beast Boy: Looks like we've got an eating contest. My money's on Cyborg.
(Other Titans stare at him)
Beast Boy: Well, if I had any money, it would be.
(After the contest ends)
Beast Boy: Dudes and dudettes, the new underworld eating champ! (Raises Cyborg's hand)
Beast Boy: (About Dr. Light) Don't we normally beat his butt by now?
YTV airdate: April 17, 2006.
This is the first non-Raven episode where the Titans battle Dr. Light.
This is the first time in the series that someone has made a psychological joke or wisecrack, being when Kole said that Gnarrk wasn't so good with people from the upper world, and Beast Boy said that Raven wasn't either, referring to episode "Nevermore," when Beast Boy and Cyborg accidentally get sucked into the portal into Raven's mind and do battle with the manifestation of her hatred for Trigon.
First episode where the Titans battle Dr. Light and there isn't any reference to Trigon.
Kole can turn herself into a crystal. She can also take in light power or lasers and revert the power beam to where she wants it to go.
