"I know it's not you."

That's exactly what he said when Light Yagami left the room after a long question. He squatted on the table in front of you, leaning towards you and turning over the key to the handcuffs in his hands. Light insisted that you wear them. But you've gained a lot more "trust" from Al because he's been following you for a long time. You didn't completely fall under the role of a suspect and he finally crossed you out, now watching how suddenly you became a suspect, being in the right place at the right time. But, Light did not take into account one thing - he did not know that in one of the recent incidents, Al asked you to come to him personally and sent a person along your route who was supposed to win you back. He almost proved that Light was Kira, but he disappeared from the cameras after he boarded the subway and did not appear during the next death, returning home slightly later than usual.
