Fyodor told Sigma to enter the houses in Yokohama, for a reason. Including your house. You've cooked some cookies. You put them on the counter, to eat them in the morning. You went to sleep after leaving them on the counter. After a few hours, it was 2 AM. He silently opened your door, walking in your kitchen. You heard some noises, it woke you up. You came downstairs to see what's happening. You saw a man eating your cookies. It seems like he got distracted by the cookies you made. He looked at you without moving. A half cookie in his hand, and other half in his mouth. His cheeks turned pink as he looked at you with a nervous gaze.
