Wow, this "leak" sure has evolved over time. That wasn't what it was originally.
It was: "Frikidoctor" (the leaker in question) said Tyrion is trialed in the Dragonpit during which Bran reveals he said he never bets against his family. It was all about how he would "betray" people and this trial was the outcome. Nothing about Dany being out of control. It sounds completely wrong now and people are trying to salvage it by adding more to it, but when you look at the source there was very little. And it didn't say who was trialing him.
Of course this makes no sense. Bran and Tyrion are now seemingly buddies, Tyrion seemingly on Dany's good side, and the "never bet against my family" thing is in the trash since Tyrion and Jaime met and what they said about Cersei.
Tyrion getting trialed for blowing up KL is going down the drain as far as I can see. That scene was more than likely a red-herring, a fake shoot. It was low budget, no green screen, and the characters present was just odd and almost every actor imaginable was in Seville at the same time coincidentally. Maisie said she was on vacation. So they paid the cast a vacation, at the same time made a low-budget fake shoot, all to confuse people.
He did NOT say Davos was in charge. He said Davos was there, and a few other characters, and he didn't know who was on the seat presiding the tiral. Characters present were: Sansa, Arya, Bran, Brienne, Sam, Robyn, Yara, Davos and Toby Osmond's character.
You guys really think they'll bring Yara back for this? And Robyn?
