He looks down at you and crouches to your height before smiling with his sharp teeth.
"Hey, kid! C'mere, I've got some magic for you!"
He didn't even wait for a response and scooched over to you. He grabbed you, picked you up, covered your head with his overcoat, and popped you into a portal.
He didn't even ask for consent :(
You opened your innocent child eyes to find yourself in a room. It's not a rubber room filled with rats that made you crazy. A normal looking children's room.
He just appears behind you from another portal he made
"Awww!!! You're so little. You stay here now. This isn't a choice, kid. This was a kidnapping."
He puts his hands on his hips and smiles again, before leaning over you and covering his mouth with his hand
"Would you like to take part in a quiz?~ Just a little trivia game!"
He laughs. Both maniacally, and somewhat... nicely. If he even has the mental capacity to do that.
