It had only been a moment. You left the plush you had made of the Duke on your table while you went to the bathroom for a moment and when you came back it was gone. You started to worry looking everywhere. Who could have taken it.

When you were about to return to see if you had accidentally taken it to the bathroom, you saw the real Wriothesley leaving Neuvillette's office with the plush you lost in hand. He probably got curious on his way to talk to the other and picked it up to show, after all it's not every day you find someone made a plush exactly like you.

When he remembered what he was carrying in his hand he went to return it to the table where he found it, but you quickly hid under it trying not to be seen.

"I'll give you back the plush of me."

He had seen you.
