"Is 'full access with equal weighting to both sets of memories' not suitable? That's what I have," says Sherlock.
"We'll be able to figure out which memory belongs to which, but having to do figuring doesn't sound ideal."
"Also I got ordered up with copies of everything she did since meeting Soph for the first time up to my existing, and doubling that up seems like it might have weird knock-on effects that mere cases of serendipity between our histories wouldn't."
"Also unlike you I'm actually eighteen and I'm not sure what this will do to my mental age."
"I think I have a protocol I like, though."
"Should I bother checking it?"
"If you want, but why bother?"
"All right," shrugs Old. "Kiss us goodbye, Sherlock, we're gonna undergo some changes."
And one of them makes a wish, and then there is one, and she snuggles up.
"Yep. I'm us, we're me, I contain multitudes, etcetera. I love you." Nuzzle.
"I should probably go talk to Soph at some point." Cuddle. "But not riiiiight now."
Before Bella has decided that snuggle time may be temporarily recessed, she sits up abruptly. "Dammit. Glory's out and I can't pentagon her away anymore and she's whining for a snack."
"Yeah. You want to come?" She squares into her clothes.
This seems like an occasion for aura. Juliet lets it pour out of her and teleports them to Glory and an instant later teleports them all three to Mercury.
Glory may recognize the voice.
"All right," concedes Bella, "nonconsenting human minds are not snackfood."
"I don't need you to like me, but I need you to quit brainsucking people."
"Is it? Do you have a way off this planet?" asks Bella, gesturing.
