Percy stood there looking at Hestia with a icy stare as she ranted about the Order and his supposed cowardice.
Let it go Perce, he thought to himself. You had a mission much more difficult than she did. It cost you dearly, including precious years with a brother you lost while fighting at Hogwarts.
He did so hope she would have the gall to attack him at the Ministry. It would be the end of her career.
His eyes followed her as she stormed off.
He did not understand how she could be so deft. The Order's vigilante status is completely unaffected by whether it saved the world or not. It operated outside the law to pursue justice, that makes the lot of them vigilantes.
