Game: You are Littlefinger, what do you do?

[Elegant Woes]

Littlefinger behaves really reckless around Sansa. I mean why kiss her so out in the open. I know some people like to believe that he did that deliberately to get rid of Lysa, but it was in his best interest to have her around as much as possible. His power in the Vale hinges on him being married with her. There was a reason why he was annoyed that Lysa insisted to have a private wedding instead of a public one in front of the Vale noble Lords and ladies. So the fact that his pedophilic tendencies towards Sansa ruined his plans to such extent should tell us that Sansa is his greatest weakness and most likely his future undoing.
