Reached a point in my book reread where I can make a comparison to this TV version. Not making any judgements or what not, just an observation:
Show: During Toranaga's escape from Osaka Castle, Buntaro single-handedly charges Ishido's samurai pursuers. We lose sight of him, and he turns up later having enlisted the aid of ronin to make his escape.
Book: Toranaga had already enlisted a bunch of ronin to hang around Osaka and be ready to aid his escape. Buntaro finds himself surrounded and outnumbered on the dock. He dumps his armor, gear, and katana into the bay to prevent their being taken, and prepares himself to commit seppuku. Toranaga orders him to run, to try and escape. Buntaro obeys, jumping on a horse and running for it with several of the surviving ronin still fighting Ishido's men.
So, in this adaptation it stays fairly close to the book. Probably easier to show Buntaro making a heroic charge instead of slowing down to explain why seppuku would have been the most samurai of acts in that situation. In the book, Mariko expresses misgivings over Toranaga's order, because Buntaro ran the chance of being dishonored by capture vs a clean, honorable death by his own hand.
