After Mori's plan failed, he knew he couldn't let Q out of sight. Locking him wasn't an option either, so he knew he had to give him a mentor. Chuuya wouldn't really be a good choice for the kid, so he gave him to you. He trusted you quite a lot.

In your office in the Port Mafia building, you read some files concerning the ADA and Guild since Mori now needed everyone to work on how to beat them. You heard your door creak silently, Q's head peeking in before he shut the door and walked in silently.

"May I come, sensei?" He asked softly. Seeing you nod, he walked foward. He had his doll in his arms as he looked up at you from in front of your desk, standing on his tip-toes.
