Game Of Thrones Season 7: 30 WTF Moments
18. Dany Destroys Valuable Supplies
It was inevitable that Dany would react poorly to the sacking of Highgarden and the murder of Olenna Tyrell, and the sequence at The Spoils Of War showing her and Drogon in full flight, burning Lannisters and Tarlys was glorious. But it also showed a stunning lack of foresight by Dany.
That's not in terms of her missing the presence of Qyburn's scorpion, or the perception that her future potential subjects will have of her burning people and terrorising everyone with dragons, but more appropriately concerning the fact that she destroys what should have been a huge bounty for her own side.
Instead of focusing her attention on killing her enemies, or the Iron Bank's gold (which would have made more sense), Dany instead burns grain supplies, attacking them in their bellies. That would have made sense if they were going to escape, but since Dany won the battle, she could have just taken the stock to feed her own army. Destroying it was just ludicrous.
