Below is the complete TOC for The Legacy of Uncle Jack, a preseries piece detailing how Wash (who seems, to me, far more likely to be the law-abiding citizen type) fell in with thieves and criminals. It covers a lot of territory, including flight school; how Wash got his dinosaurs; why Wash dislikes gun hands; what happened when Wash met Zoe; why there seems to be some confusion over just what his name is, exactly; and why Zoe had her necklace before she met him.
Rated T overall for mild language and action-y stuff.
One. Two. Three. Four. Five. Six. Seven. Eight. Nine. Ten. Eleven. There's no money in fanfic; I work for feedback. Let me know what you think!
