"Oh don't start with me, brat," he rolled his eyes, not at all threatened by a little kid with no magic. Muggles were very silly. "I'm not bloody well keeping any of it and neither are you. You don't need to knick things when you've got magic anyhow so stick with me, you'll be fine." And there was no way he was going to start explaining that his dad and his uncle were sort of wizard cops so his arse would be grass if they caught him.
"No one's brother is cooler than me, trust me on that," Jamie smirked with a confidence that wasn't quite all there but certainly put on a good face. He gestured with his wand towards a door that opened, "Kitchen's that way - I assume. It's the only room I didn't look into before." The dogs and the cats alike all started through that particular door.
