When Luke rescues Leia from her cell on the Death Star:
Leia: Aren't you a little short to be a stormtrooper?
Luke: Huh? Oh, the uniform. I'm Luke Skywalker. I'm here to rescue you.
Leia: You're who?
Luke: I'm here to rescue you. I've got your R2 unit, I'm here with Ben Kenobi!
Leia: Ben Kenobi, where is he?!
Luke: Come on!
How does Princess Leia know Obi-Wan Kenobi is "Ben" Kenobi?
Shouldn't her response have been: "Ben Kenobi? You mean the General??"
