He didn't expect this anymore. Even more so after you, his own daughter and Leia's. Of course - he knew that you were a Force User, you know, that's what he supposedly called the Skywalker blood, but... he didn't think that you would take such a big step with your desire to join the empire.

He felt betrayed - after all, you were still his child. And even more during your reunion, he couldn't help but be sarcastic... He missed you.

“You look old." He said sarcastically. You've grown up.
