Margaery: Cersei is not here. Tommen is not here. Why do you they are not here?
High Sparrow: If the accused is not here, she will be tried regardless. We cannot escape the justice of the gods
Margaery: Forget about the bloody gods and listen to what I'm telling you: Cersei understands the consequences of her absent and she is absent
anyways, which means she does not intend to suffer those consequences. The trial can wait. We all. need. to leave.
