Ron could see the resemblance to George now, in the shape of her nose, in the way her jaw set so stubbornly. He wondered who her mother was, though he could make a fair educated guess. He kept his hand over hers, trying to project a level-headed calmness that wasn't a natural state for a Weasley.
"I know it's not funny, and I'm sorry but it's not a prank. I really, really wish it was." He wished he could shout surprise! I was only joking, if only because the look on her face made him want to cry. "Everyone died, and Hogwarts decided that wasn't okay so it brought us here from all different eras and times. So far, you're only the second one from your time. Savannah Monroe arrived a few days ago from...2028, or somewhere around there."
He squeezed her hand again. "It's a lot to take in all at once, and I'm probably the worst person to explain it all." He smiled a little. "And this might be weird, but it's really nice to meet you Roxanne. It will be good to have another Weasley here. I'm not used to being the only one." And it had been weird in a way he had only just noticed now that there was another Weasley here.
