Feast and Dance happen at the same time.
Plus, in the chapter you’re talking about, Cersei III: she is literally using it to burn down the Tower of the Hand purely because she’s so mentally ill she believes Tyrion is living inside the walls somewhere. And she starts marvelling at the flames and looking like some kind of pyromaniac nutter to all bystanders.
If she’s willing to burn down the tower of the hand to kill Tyrion (who isn’t even there, she’s just a schizo), why wouldn’t she burn down the Sept to kill the Tyrells? It’s not like rationality or concern for consequences is her strong suit, and it’s already well established that she hates Margaery almost as much as she hates Tyrion.
Does GRRM need to have it announcing itself with bells on in every chapter?
Plus, now apply this logic to position I’m arguing against. When do the Tyrells ever express any interest in Aegon and friends or vice versa? Literally never.
