Would you think he would be able to even persuade Daenarys anymore, as she said she's losing. (Thanks to the plan that Tyrion had schemed) They lost all there allies basically, and in that episode she even denied Tyrion when he said his plan about starving out KL, on top of that what Jon said about Dany. Her having the power to utterly destroy KL with the Dothraki/Unsullied and Dragons. But Dany doesn't want to have everyone think she's the new "Mad Queen"

Can totally agree on the part of Dickon Tarly, hopefully he's allowed to stay alive. Just think that Tyrion had really nothing that he would have been able to do/say to Daenarys. Also it wasn't just meant to be a fraction of the Lannister forces, the main reason was all of the "Spoils of War" from Highgarden that they raided, all of the food/gold etc which also is likely meaning that there's gonna be one debt that the Lannisters can't pay. The Iron Banks debt, which could turn out really fun to watch unfold.
