No final de Harry Potter e a Pedra Filosofal, Voldemort ordena que Quirrell apreenda Harry.
Harry sprang toward the flame door, but Voldemort screamed "SEIZE HIM!" and the next second, Harry felt Quirrell's hand close on his wrist. At once, a needle-sharp pain seared across Harry's scar; his head felt as though it was about to split in two; he yelled, struggling with all his might, and to his surprise, Quirrell let go of him.
...
"Seize him! SEIZE HIM!" shrieked Voldemort again, and Quirrell lunged, knocking Harry clean off his feet' landing on top of him, both hands around Harry's neck -- Harry's scar was almost blinding him with pain, yet he could see Quirrell howling in agony.
"Master, I cannot hold him -- my hands -- my hands!" And Quirrell, though pinning Harry to the ground with his knees, let go of his neck and stared, bewildered, at his own palms -- Harry could see they looked burned, raw, red, and shiny.
Anteriormente, Quirrell havia amarrado Harry com cordas.
Quirrell snapped his fingers. Ropes sprang out of thin air and wrapped themselves tightly around Harry.
Por que Quirrell não fez o mesmo quando recebeu ordens de Voldemort? Mesmo se não tivesse ocorrido a ele, por que ele não o fez depois que percebeu que não podia tocar Harry com as próprias mãos? Ele poderia procurar Harry pela Pedra Filosofal sem ter passado por todos os problemas. Considerando o quanto os adultos bruxos confiam em suas varinhas (ou pelo menos em alguma forma de mágica) para realizar suas tarefas, parece ilógico Quirrell mergulhar fisicamente para prender Harry, quando ele seria capaz de mantê-lo parado com um piscar de olhos. dedos.
