I take it you think you are being amazingly witty and clever to keep trotting out this widely-debunked, nasty and vile rumor about Harry’s father. It has been put to rest long, long ago, except for people who enjoy calling others bastards and thinking others’ pain is enjoyable. You stay classy, hear?
Based on her story that she didn't start with him until after Harry was born? The testimony of the adulteress is not exactly probative on the issue.
Or are you suggesting that we should be looking at one of the other lovers. He wasn't exactly the first, was he?
