Guess I did...cause entrusting the entire kingdom in a crucial time of war to somebody you previously figured was a worthless whoremongering drunk seemed to me a lil more significant than trusting your fukk up son to pick up your dry cleaning or something...at the very least it seemed to suggest he had more trust and respect for Tyrion's competence than Cersi/Joffrey or anybody else he could have propped up in his place..just doesn't make sense to me why they'd go from where they left off to all of a sudden him not caring if Cersi had him killed for no good reason so much that he had to hide in his own city...considering the only thing that happened in the interim was Tyrion doing what Tywin sent him to do with great success...had it not been from Tyrion, Kings Landing would prolly been burned to the ground by the wildfire instead of destroying Stannis' fleet and giving them a fighting chance till Pops and the Tyrells got there
I hear you, its just that at the time of him giving tyrion the job there was no one else.
As for the aftermath of the battle, well "history is written by the victors" tyrion has got noone to back him up cos everyone around him he had to pay for, so someone paid them more, apart from the homie Pod, the wildfire was never his idea in the first place and it ended up being that faq carcetti that saved the day.
And fam. Tywin's cold, who is he gonna back, his grandson The King and his daughter The Queen Regent or Tyrion.
Its easy to feel bad for Lil Man but dude was playing too many sides and it caught up with him, being the Hand of The King is a shyt job.
