The Doctor watches and waits to see what the troopers will do. The Doctor breathes for a moment in his mind and tucks the psychic paper back inside. He does notice the red beam pointed at his chest. Blimey, he just died, he really doesn't want to - again and is also sort of tired and frustrated with this setup but keeps it together. He gives a head nod in reply and begins to start climbing the wall. While, he starts, remarks, "Don't carry weapons, me."

Then - slips, and begins to slide back down, in a frustrated sound remarks to himself, "Need to get used to longer legs again."

Eventually, he does make it over and takes it slow with his hands up.
