I don't want to be there when they find us. At least on another ship we'd have a chance at graduating without the Admiral's warrant hanging over our heads. Besides, I want to keep an eye on Bill, and that'd be easier with you along. What do you say?

[That last bit is said more gently than the rest. It's the tone instead of the words that says that Ford genuinely wants Luke there, and not just as Bill's warden. He likes the guy, he's just garbage at actually using his friendship words.]
