I don't understand the point of these lines. Vader wasn't surprised that Ben was alive in ANH. Furthermore, he thought Ben was dead and gone for good in ESB. "Obi-wan can no longer help him."

Well, for believability sake. If Vader didn't believe Obi-Wan was dead, wouldn't it be a priority to kill the only Jedi left alive who had and possibly could defeat you in the future?

But the second group of lines I did, I like much better.
