It wasn't as though she'd never considered the idea, but somehow hearing him say it hurt. "No," she said quietly. "We have to get back. Remus remembers me older, and Neville knows my son. I ... if I'm here, stuck here forever, how can they remember those things if they never happened?" It was a paradox or an impossibility or an instance of alternate realities, but if she was here she couldn't be there, and if she wasn't there, how did other people remember her being there?
Honestly, it was enough to break her brain if she thought on it for too long.
She didn't exactly have a better theory to counter his though, and she stared for a moment at the tabletop where the glass had been. They had to get home. Somehow, some when. This couldn't be forever. This wasn't her life, wasn't her world, how could she truly be stuck here?
Turning her emerald eyes toward him, she sought out some sort of ... something. She wasn't even sure what she hoped to see. Her lips parted before she sighed and looked away. "I ... I can't say I like the thought of ... of being here forever."
