Ron Weasley - Rose Weasley - OPEN.
You didn't really need to know the layout of the building to cast protection spells, she and the others would just have to walk the perimeter later and make sure they got it right. Mostly she was curious about muggle apartments. So when she stepped to one of the rooms, she flicked the light switches on and off for a moment. Of course she knew all about lights, and television, and some muggle appliances, but that didn't mean she didn't get a kick out of them every time. It wasn't often she was around them, only when she visited her Grandparents, so she really only knew the basics.
She vanished into an apartment and made her way to the bathroom. Flicking on the lights, her eyes narrowed when one of them made the light red. She looked up at the ceiling in confusion. Stepping in the bathroom, she noted that when she held her hands up to the light, it was warm. A red light that heated that bathroom.
With her mind, it sounded both hilarious and useful at the same time. Snickering slightly, she walked back out again, flicking off the lights. Would she end up with her own space, or sharing with someone? Actually, she planned on expanding it if she could anyway, so what did it matter? It might take her a while to get it right, but wanted to give it a shot.
It was too bad they couldn't use some of the spells her parents must have when they were hiding. But too many people who were muggles needed to be able to find this place.
Leaving the apartment, she went in search of someone she knew. It took a little while but soon she was on the second floor. At first, she walked right past the room that was wide open. But when her mind clicked on who she saw, she froze, and then back paced. Eyes rolling, she moved as silently as she could until she was as close as she could get without him noticing. "You!", she said, using her best Hermione in impression. "Are going to be in so much trouble if mum finds you up here." she said, her expression amused as she looked down at him with eyes that matched Hermione's perfectly.
