What's the offense exactly?
Also I don't really get that 3PO fact bit, so he won't divulge any of his former master's secrets....
What secrets exactly? Luke already knows about the trouble Leia is in and later gets the full recording.
3PO notes his last master was Captain Antilles, who I don't think would have anything worthwhile other than the mission that Luke finds out later. He was mindwiped after EP 3 so he wouldn't have anything else.
