  Nothing else could be said before Harry heard footsteps approaching. Quickly Harry hid behind a pillar on the other side of the room. Then bursting through the flames Professor Quirrell came inside. He began muttering about the Stone and how to receive it, with no stutter. Harry was breifly shocked about the fact before he thought back. The stutter did seem slightly fake and more importantly, it was a good ruse. In front of ex-Death Eaters such as Snape and Carrow who would think Quirrell was anything less than a stuttering idiot.
