A reporter asks Ben if he is dating Jennifer Nocturne. Jennifer Nocturne appears in the later episode "Hero Time".
This marks the first appearance of Ultimate Big Chill. It is the fourth ultimate form of an alien seen, and the third one used by Ben.
Alien Forms Used:
3) Big Chill
4) Ultimate Big Chill
Charmcaster is shown in possession of Hex's staff. As stated in the original series, only a master magician can use it. Since Charmcaster was able to do so, it implies that she has become a master magician since her appearance in Ben 10: Alien Force.
Gwen: Do your worst.
Zombozo: Not that I need your permission, but that's exactly what I had in mind.
Zombozo: Ladies and gentlemen, and victims of all ages, welcome to the final act. I promise it'll be a killer! (cackles evilly)
Kevin: Used to love carnival rides. Now they just make me sick.
Charmcaster: You have precisely the same effect on me.
Charmcaster: I've waited a long time for a rematch, Gwen.
Gwen: Careful what you wish for.
Featured Alien: Ultimate Big Chill
Ultimate Big Chill looks much like Big Chill, except that his body is now red instead of blue and the brows around his eyes now look like flames. Furthermore, he is capable of shooting flaming ice which look like fireballs capable of freezing. It is implied that it can also burn, but that ability has yet to be seen.
Ben does not recognize Zombozo at first, having completely forgotten about their previous encounter.
Note: According Dwayne McDuffie, Ben only pretended not to remember him because he didn't want to admit that he used to be afraid of clowns.
John Kassir does not reprise his role of Zombozo from Ben 10. Instead, John DiMaggio voices him here. Kari Wahlgren voices Rojo who was previously voiced in Ben 10 by Jennifer Hale.
It is shown that Gwen can change in her Anodite form.
Gwen's method of confronting Zombozo is very similar to what Raven did to Dr. Light in "Nevermore" on Teen Titans.
Zombozo's new modus operandi - using clown props as deadly weapons - mirrors that of the Batman villain The Joker.
