I think I can solve some of struggles in this story by starting later, and backfilling the set-up if I genuinely need to. I could probably just start in the studio with the other characters present. I could do a dialogue scene and avoid the many problems a "character alone thinking" scene creates. I can use the other characters to backfill the other set-up I've convinced myself I need to have. It also lets me put some of the ideas I was trying to work in a stronger context. I forgot the golden rule of short fiction. Start as close to the ending as possible. I'll experiment a bit.
