You missed the fact that he shot her with shotgun shells loaded with rock salt, not shot. As Budd told her, it'd sting, but it won't kill her. Personally, I loved this second half. It doesn't have the same visceral impact of Vol. I, but it wasn't meant to; this is supposed to be the contemplative half of the film, wher we figure out why The Bride really left DiVAS, and the end really brings it all together, especially if you have any understanding of psychology.
