The Doctor ground his teeth together, hard. I know. It was right there, in that instant. It was acceptance and reassurance as best he could manage, but there was also so much strain there, as he pushed back against the Drums, doing everything in his power to get the things contained, muffled, far enough that the Master could finish getting them out, but that really was the best he could do. He couldn't drag them out for the Master. It was taking everything he had to do this. Literally his mind burning brighter, almost white in the Master's. And it hurt.
