I liked it that Littlefinger finally got what he deserved, and had no sympathy for him. He reaped what he sowed.

However, I was bothered by the fact the whole "trial" was a farce. Sansa could have simply sentenced him to death right away. The only difference between that and Tyrion's two trials was that Tyrion was innocent.

First, what evidence did Sansa present? Bran's ability to see past events. This is as "conclusive" about as testimony given under hypnosis. There was one witness who could testify about Littlefinger's act of pressing athe dagger at Ned's throat during the massacre in the throne room - the Hound. Why not call him?

Second, regarding Lysa's murder: didn't Sansa lie brazenly to Lord Royce about it? She definitely did ("The Mountain and the Viper"). Now she is changing her version simply because she is in power position. That was a perjury.

Third, what Arya said "You told our mother this knife belonged to Tyrion Lannister. But that was another one of your lies. It was yours". That's a total B-S: Littlefinger never denied the dagger originally belonged to him - he said that outright to Ned and Catelyn ("Lord Snow"). He lied about the identity of the person to whom he lost the dagger in a bet, which has never been revealed in the show for some odd reason (Robert). Arya's accusation can be interpreted as if Littlefinger had some secret way to possess the dagger even after he lost it, and that maybe he somehow armed the catspaw assassin with it, which of course he didn't - he wasn't at Winterfell then (in the third novel, Jaime and Tyrion figure who hired and armed the assassin).

Fourth, Sansa was disqualified from being the judge, because she was not objective. She was harmed as a result of Littlefinger's deeds - she said that herself, he sold her to the Boltons.

If Littlefinger had time to think it over, he could easily refute all the accusations, but it happened too fast for him.

What did you think about the trial, other than satisfaction about Littlefinger's fate?
