"Stupefy!" said Blaze and stunned him just as Sarah had let him go. He looked at her with a bit of disbelief. Then back the man. "If im not wrong this is one of Voldemort's less important death eaters. He's a small time criminal, thinks he's one of the best assassins. I wonder why he came here" said Blaze who thought being in Hogwarts would be safe from now on, obviously it wasn't.
He then looked at Sarah, still astonished that she used the curse. He didn't really feel like saying much, he binded the man and looked back at Sarah, almost in search for an answer.
