[spoilers] Sir Harry Pearce 2.0

[Silktie]

It's possible, Aria, but I don't see what threatening Harry with exposing the affair would gain her. It's not as if he's still married, and an affair is not actually a career-ending move nowadays. She would have more to gain by threatening to tell that he covered up the fact that things went wrong on the operation because he acted against orders, and then covered up the fact that it caused someone's death. That part would not be on file anywhere, as only Harry knew and he covered it up.
