Sure. The tf was to show that there is definitely some kind of 'link' between these entities in the other world and on Earth. I am considering what effect this has on the 'real Steven' but not sure yet.
The trait stealers are essentially vampiric. If you kill them they release all the traits they have taken back to the bodies. (Though with the right magic a trait steeler can also bestow a trait to somone else... Guess which world has the most 'traits' of all. I just figured we haven't seen a tf in ages so just threw one in... I know people want a tf more then anything and it's a rare female to male one.
I figured though I should examine things on earth a bit with Jen, her family, and the interaction with the new kids. Writing about an exotic family is fun, though I must admit post tf stories are very tricky. I should have planned this better...
...still need to figure out what happened with the clockwork planet and the thee lights magic girls as well as Anezza. Eh, I need to make a chart of all these characters.
