Selfish he can handle. A minute ago he was sure she was trying to chase him off; if she's not, then hell, she can hang on all she wants to. He curls his fingers around her hand, warm and sturdy, reliable. Except he's still totally confused about what she means.

"Because he killed Luke's--" your, he should've said-- "father?"

It's halfway between statement and question. That's what the old man said, isn't it? And what difference does it make, anyway? He's not in love with her father, after all, whoever he might have been. Whether he was a senator or a spice runner or a Jedi, it's all the same, doubly so if he's dead. The only reason he can see not to declare himself too drunk to have this serious a conversation and forget it is that Leia's clearly tied herself in a knot, which means he needs to help untangle it.
