The Slytherin common room is cold and uninviting.

Snape billows in, bringing with him dead silence.

"What are you waiting for?"

Slytherins scatter. Moments later the common room is empty.

He meets Snape's eyes.

"You brought this on yourself."

He knows it.

"The Fourth Year dorm is through that door."

His knees threaten to buckle.

"Don't expect me to intervene on your behalf."

Of course not.

He stays silent too long and Snape grabs him by the shoulders and shakes him until his teeth rattle.

"Don't you have anything to say for yourself?"

But he doesn't.

Not a damn word.
