both GOT podcasts I listened to the week before said her heel turn was inevitable

Tyrion said in the last episode he didn't want to hear the sounds of women and children burning and screaming

I thought her heel turn would wind up being a tease, and I think most of us (and Tyrion) only expected it as collateral damage (her being reckless and dgaf with Drogon vs straight up genocide), and I have complaints that beats are missing but its also BS to claim there were no signs. she literally talks about laying waste to cities multiple times throughout the series
