Well, there's still the Continuum-Unending puncture for Cam planned, but I don't know when that will happen, because I don't want to do it without knowing what happens in the damn iTunes-only narrative. Ridiculous backstory idea

There is Elizabeth, though. She doesn't have a lot of plot coming up, so something could be done with that?

Also, I'm fairly certain there are purple guys around. I know there's a mauve-dude in s1 Farscape that could theoretically be used, too. (That Old Black Magic, I think)
