Angst
He sat in the Torchwood cells. He felt alone and afraid.
He felt like the kid he had been once.
He was no prisoner. He had chosen this spot for his moping. He had chosen this spot because he knew it would make him feel alone.
He didn't know what he would do. He didn't know how he would cope. What he had done in the last five days was worse than anything he had done in his entire life.
He was a terrible grandfather and a terrible lover.
He was the cause of their deaths, and it haunted him.
