Maybe something is starting to form. This may be a snippet? Not sure.

How long had he been staring at the other?

How long had words been whispering in his ear?

They were cold and slick and enticingly attractive.

They were telling him to kill.

They wrapped around him like the robes he wore, always waiting. He wouldn't do anything just yet.

He'd continue to stare at his cell mate and wonder.

How long until Draco noticed?

Not long at all.

"H-Harry?" Draco shuffled from his corner, crossing the small cell in two great strides. His hands went directly to Harry's shoulders. He had to make sure that this was real. "You're back." He whispered, almost talking to himself as his fingers dug into Harry's arms.

Harry stood, his body tense at the touch. There was an underlying sense of foreboding between the two and hadn't Harry come in to do..something?

Do it…

So easy…

He wouldn't expect it…

Now

Harry shook his head and backed away from Draco. He could feel the force within him pushing him to complete the task he was set to do.

So easy…

He felt his back hit the wall as he slid to the floor. Draco was at his side within seconds.

"What's wrong?" The blonde asked, concern written all over his face.

Harry dared a glance up at the other.

Now

Pushing Draco away, a bit more forcefully then he meant to, Harry brought his hands up to his face, dragging them down as if to help shed the voice inside.

Do it…

"Draco..just stay away from me." He muttered the words almost too quietly but Draco heard them all the same.

It had been a while since the two of them had come to a mutual understanding of friendship in this place, but with those words any trust building within Draco left. He shuffled back to his side of the cell, wrapped himself up in his tattered robes that hung off him a bit more then they usually did, and promptly began to ignore Harry.

Good.

Let him stay away.

The force within pushed once again but Harry just laid down where he sat and rolled over to face the wall. He suddenly felt cold and though that normally meant a huddle for warmth between the two, Harry was glad for the first time in a while that the cold seeped deep into his bones.
