Maybe him being in pieces overrode his etiquette. But hold on, he calls him "Han" in the asteroid belt too! I was thinking only of "We're trying to save Han from the bounty hunter!" So not that then...

I can't believe I'm joining this argument, but when 3PO says to R2 that they are trying to save Han from the bounty hunter, keep in mind that he was addressing R2. If ol' goldenrod was talking to a human, he may have used 'Captian Solo' instead.

But it's just a movie, so I'm not gonna sweat it.
