The Doctor was listening to the conversation with a mixture of emotions running through him; really, it was getting to the stage where he was sick of listening to Valek's nonsense, and he was bored with years of listening to the Master's threats. He half wanted to ask if he could go and have a shower while they figured out which of them was going to be his torturer.
He stood up, dusting himself off a bit before crossing his arms across his chest moodily. He knew that the Master wouldn't just walk away, especially not when Valek used the word 'allow'. No one 'allowed' the Master to do anything.
