Amy notices the tension across his shoulders, the tightness of his fists. She knows that his words are dark and lead down a path he rarely ever follows. She swallows hard at that realization. Unlike her own Doctor, she doesn't know how to stop that anger. She doesn't know the words and actions it takes to pull him back to the brink. A part of her isn't sure she even wants to stop it.

That thought stops her cold. What has always set them apart from monsters is their ability to reason and empathize, to rise above the darkness of revenge and hate. In all her years of travel, there haven't been many monsters. The Daleks, the angels, but rarely ever humans.

Whatever is causing all of this, that is the monster. Not them. Resolute now, Amy steps up to the Doctor's side and places a hand on his arm. "They won't. Not if everyone here has anything to say about it. One way or another, we'll set this right."
