It was a black tie with a blue swirl across the side. It might've been the Doctor's tie, if it wasn't so dark. That was the Valeyard. Living the Doctor's life, but with a level of darkness the Doctor refused to reach.

"If I rest more during the week, I think I can have longer," he added. His voice was still quiet, he still conserved his energy. He looked over to the Master like a starving man looks at food. His oldest enemy, his only friend.
