With the exception of Trance Gemini, Flux is the first Celestial Avatar seen in the series, and the first proof Trance is not the last of her race. At the beginning he acts like an overly strict valet or manservant, but in his later exchange with Trance it is clear he is far less invested in his companions, and even the outcome of events, than she is. He views those with him as necessary tools and lesser beings in a way which only rarely and briefly appears in Trance's behavior. ("In Heaven Now Are Three")
Flux: Looks like I'm not the only one with a new look, Trance Gemini. We thought we'd lost you.
Trance: And that's why you're here. That's why they're here.
Flux: Well, someone has to retrieve the Engine of Creation. It doesn't really matter who.
Trance: It does matter. Maybe not to you or to our people, but it matters to the Engine.
Flux: Ooh, interesting move. I didn't even see that one coming.
Trance: They've done it. Dylan and Beka have won.
Flux: Well, like I said, someone has to retrieve the Engine. We all know what happens next.
Trance: Some of us better than others.
Flux: Come with me. Your brothers and sisters would love to know what's become of you.
Trance: No. My place is here with my friends.
Flux: Your place is with us. Don't forget whose side you're on.
Trance: I never have. I never will.
Flux: You can't defy us forever, Trance.
Trance: No. But I can dream, can't I? Even if it's just for a little while.
