The spider like forms that had gathered moved to circle the Doctor when he had arrived and just as he approached Amy, they cut him off. They seemed to collapse down, their limbs folding into an odd flower like shape, upwards, rigid and crooked. The next thing the poor Doctor would see was a barrier forming, connecting from collapsed form to form, and webbing itself around the Doctor, up towards the ceiling. An energy barrier... orange, that crackled and glimmered oddly.
And then it came again. That tapping, in sequences of four.
The Doctor was cut off from Amy now. The strange figure stepped out from the shadows and approached the barrier, his face still shrouded by the hood. "Doctor... Doctor... Doctor... Doctor... You never write, you never call... it's as if what I did for you didn't matter at all... I'm wounded" he said in a mocking tone.
