He knocked on the door, repeatedly. After about twenty knocks, the door finally flew open. "Why the fuck are you bothering me?" Jon was nearly knocked down. First, because of the way she talked, and second because she looked different. She still wore the Goth clothes he saw her in before, but now she also had black lipstick and eyeliner. She must have put it on after she threw him out of the room.
He gulped, suddenly tongue-tied. This was his mother, but...she was so intimidating like that, he tried to speak, but after a moment, she slammed the door on him. This time no amount of knocking would make her reopen it.
He decided that she was probably harmless and safe for now. He would get back to her later. There were other things to do.
