How is it that olenna Tyrell is the only one aware of the machinations and penchant for mass murder of Cersei Lannister. Cersei was accused of regicide in a very public trial, at the very least of all KL knew about it. Then the day of the trial all her enemies get blown up...

KL is about half a million ppl yet there seem to be no reaction at all to a major part of that city being blown up and many ppl dying

Now if u want to chalk it up to weariness or fear that's more believable but seeing seemingly no reaction was kinda odd but I guess they wanted to just keep the story moving
