The Doctor watches during the silence, trying to get more of a read on the other man but someone seems to be a trained soldier and usually, the job is to not express emotions. He does wonder what the other is seeing because sometimes the psychic paper doesn't work. Either The Doctor is lying too much and claiming to be 'responsible' or the other is too smart, like Shakespeare.

However, he's not dead - yet. So that means someone is still useful. The Doctor remarks calmly, "I don't know who you are. I saw you running and usually when you're the one running away, that means the other thing is chasing you and most likely trying to kill you... Yeeeeeeeeah, the thing is - I'm not exactly sure where my ship landed me."
