What's with Threepio not being able to control his actions but at the same time being fully self-aware when his head was attached to a B1 body? Isn't his "brain", or CPU, supposed to be in his head? Why couldn't he control the B1 body? Why would he randomly say "DIE JEDI DOGS" and compulsively shoot at everyone? Do B1 droids have some kind of CPU or behavioral module in their bodies that takes over? Because B1 droid head that was attached to Threepio's body was fully aware of his function as a B1 droid and said that he couldn't move for shit, so his CPU was clearly in the B1 head and was fully in control of Threepio's body. What the fuck was even the point of that entire sequence anyway?
