Zee: There is one chance. I may be able to control his warming with my own internal heat element.
Ro: Hold it. You're going to walk into that gas to get him?
Zee: I have to.
Ro: You saw what happened to that cart. How do you know it won't happen to you?!
Zee: I don't.
Ro: Did you forget you can't fly again?
(As sirens blare)
Ro: Ah, they're playing our song.
Starting from this episode, the opening sequence has changed. The theme song is still the same, but now clips from season 1 episodes are seen rather than Zeta running from Agent Bennett and his crew while meeting up with Ro as seen in the season 1 opening sequence.
This episode was originally produced as part of the first season, and aired 5 Dec 2001 on the Canadian YTV channel. However, when it premiered in the U.S. to begin the second season, its opening credits had been updated with shots from later first season episodes and some second season stuff as well, although they feature the same music and opening and closing narration.
