The Master mentally sighed at the Doctor's response, the other's frustration mirroring what he'd felt for years and threatening to break the seal on his box, though he was so wrapped up in everything else that was going on in his head that he didn't even register the cracks oh so slowly creeping across its surface. He let a little bit more of the drums through, certainly not at full force but still more than he had before in the hope that somehow merely increasing the quantity of the noise would increase the quantity of data relating to it and thus help them figure it out. He didn't have high hopes for this particular vein of thought, particularly since every time he let some small additional piece of the drums through his general control slipped just that little bit more but at this point, he was rather desperate and willing to try just about anything if it meant figuring out and hopefully stopping whatever was causing them.
