Hermione

Harry decides that Hermione is a better choice for him, and apparates over to her parents house and knocks on the door.
John Granger, Hermione's Dad, answers the door and invites Harry in, looking very excited to see him for some odd reason.
Jane Granger, Hermione's Mum calls out to him from the kitchen, and puts the kettle on.

John and Harry talk about life for a moment before he asks if he can see Hermione.
John says that she should still be upstairs, where she's been all day.

Harry thanks him and climbs the stairs to her bedroom and knocks on the door, there is no response so he tries the handle, and the door opens without a hitch.

Harry peers into the room.
What does he see?
