I would prefer Tyrion to betray Dany than to just become a useless idiot. He was a brilliant Hand under Joffrey, and he's become completely incompetent under Dany. He comes up with this idiotic plan to send everyone to capture a wight. Then when they get stuck there, he tells Dany to leave them. Politically, neither the North nor the Vale would ever help them if their king never came back from Dragonstone. And of course, Tyrion's plan hands the night king the one thing he needs to destroy the wall, PLUS Cersei still won't help them. And they have lost Dorne and the Reach (although Dorne should still support Dany, because they hate the Lannisters). Basically, Dany needs a new Hand.

There were a few issues here: 1) As Littlefinger himself said, none of them were there and they had no way to prove it. Why admit something they can't prove? 2) The Vale lords don't even question why Sansa is matter of factly stating what she so emphatically denied before. She swore that her aunt committed suicide because she went insane, and the Vale lords bought that story hook, line, and sinker. 3) The most serious charges against Littlefinger were murdering Lysa and selling Sansa to the treasonous Boltons. These are both things that Sansa already knew about. Yet she sat in Winterfell with him for months and did nothing. Arya finding the letter and having the dagger, or Bran knowing that Littlefinger told Ned not to trust him, added nothing to him being found guilty.
