Makes perfect sense that the Solos would find a way to rise in an unsure situation. Ditto that the Empire is not accepting the status quo. Palps was probably re-calculating his plans from the moment Mace and Anakin got clear of him.
Kie-wan's existence makes sense to me as well; less so Lance's, since I thought the Organas couldn't have children, but his L-name suggests something. I have all kinds of guesses, but instead I'll just let you keep telling this great story, but with one question : Does this Luke have anything going for him? It seems like Anakin might have kept him down better than Owen could ever hope to.
