It had been almost a week since visiting Hagrid, and Dazai 's meetings with Quirrell had suddenly stopped. Dazai supposed he had finally pushed the professor too far 'too many tight-lipped smiles, too many subtle jabs, too many questions about Quirrell 's various criminal enterprises. Too much.

It was all very entertaining.

It had also been about a week since Dazai had told the twins (and by extension Ron and Blaise) of his plans to steal the Philosopher 's Stone for himself. They were ecstatic at the prospect of a prank with such epic proportions. Tricking their classmates? Easy. Fooling their teachers? Simple. But interrupting a criminal heist with their own? Perfect.
