Tenho a impressão de que eles realmente não fizeram como o próprio Tyrion afirma:
Tyrion: Me? The Imp? Half the people hate me for serving Daenerys, the other half hate me for betraying her.

E, na verdade, eu não acho que eles estavam realmente tentando libertá-lo, ele foi levado para lá, no julgamento, para que eles pudessem decidir o que fazer com ele, se isso o libertaria, puniria ou qualquer outra coisa.
Where's Jon?
Grey Worm: He is our prisoner.
Sansa: So is Lord Tyrion.
Grey Worm: They were both to be brought to this gathering. We will decide what we do with our prisoners. This is our city now.

Eles também não pedem a opinião de Tyrion sobre o que fazer, ele apenas vê uma oportunidade e a oferece.
Tyrion: Jon committed his crime here. His fate is for our king to decide. Or our queen.
Yohn Royce: We don't have a king or queen.
Tyrion: You're the most powerful people in Westeros. Choose one.

Por fim, Tyrion é libertado porque Bran o nomeia Mão do Rei e decide que ele deve ser libertado. Como rei, ele pode fazer isso, não porque todo mundo lá queria que ele fosse libertado.
Bran: Lord Tyrion you will be my Hand.
Tyrion: N-- No, Your Grace, I don't want it.
Bran: And I don't want to be king.
Tyrion: I don't deserve it. I thought I was wise, but I wasn't. I thought I knew what was right, but I didn't. Choose Ser Davos. Choose anyone else.
Bran: I choose you.
Tyrion: You cannot.
Bran: Yes, I can. I'm king.
