In her space life, Thorn(e) was Char, the chief mythic designer up until five years ago. She and Jackie had roughly parallel careers?

So far we're thinking:

-- oops baby happened seventeen years ago
-- busy couple maybe didn't realize until it was too late to get an abortion or Char/Thorn was opposed to it
-- they thought they bargained to have it go to the mythics after it was weaned using their positions within the Producers to get away with it
-- went back to their normal lives of memory tech and mythic designer
-- five years ago after a stupid fight over a ruined article of clothing, Char stays late at work and idly combs through the new actor database to see who she might have to design for in the future
-- guess who just got entered into the active actors because he got his first job
-- instead of going to the mythics they kept him to be trained as an actor
-- THIS WAS NOT WHAT THEY AGREED TO
-- Char/Thorn storms into the office for the head producer and is never heard from again
-- and Jackie finds out what happened while he's erasing her memories OOOPS
-- and then takes five years to get his shit together

Hopefully that can work?
