Frankie nodded. "Yeah," he said solomnly. "Me too. And I hope Grandad comes from earlier, so he doesn't have all those crap memories. And I hope they remember each other so they can be happy, like your grandparents. But that probably means I've jinxed them into arriving as six year olds, if they ever do." He sighed a little.
"It worries me a bit," he added after a moment, scuffing his shoe. "That Mum might go. I thought she was pretty much permanent here, but that was what we thought with Mr M., right? And then if she comes back younger, what do I do?" He made a face. "Need to stop worrying about stuff like that, I s'pose. Not like we can control it or anything."
