Is it odd that Baelish is kind of stealing the show for me? I love the way he twists and plots things like that, its like he's so deliciously evil and I'm really curious as to how he'll move forward. I do have a question though, does this technically make him Lord of the Vale since he married her? Or does that title still remain in the hands of her little shit-head son?
I think my two favorite characters in A Song of Fire and Ice are Littlefinger and Varys, because they are the only two characters, it might be argued, who truly know how to play the Game of Thrones (although an argument can certainly be made for Tywin Lannister and Olenna Redwyne, otherwise known as the Queen of Thorns). Both of humble origins, they have risen to positions where they pull the strings to make houses rise and fall.
As for Baelish, unless I am mistaken, he is now the Lord of the Vale, although there are some, such as Bronze Yohn Royce, who oppose him. Since he has the backing of King Tommen and the Lannisters, however, he's pretty firmly seated.
