Hmm...other than the almost word for word match to the opening 10 min of "Serenity," this opening chapter really blew me away at how you've managed to meld the three disparate storyverses together. And even basically copying Whedon's dialogue and scenes isn't the epic fail it could have been because you used the existing awesome intro and subtly added the necessary parts to allow the HP portion to be integrated into the mix smoothly.
Gotta wonder though...we gonna be seeing the "Serenity" crew in this, cuz if the Republic is pre-Clone War, then I doubt we're gonna be seeing Han, Luke and Leia ;D
