[I doubt that would help. You'd probably both still want to hug both of us,] Bell points out.
"I should've never - ever - happened," says Shell, "it should just be you - how long has it been - what did I miss -?"
She contemplates actually making this wish.
To Shell, she says, "All I know is what you told Sherlock. Do you mind if I look?"
"You can look, you can both look, you can do whatever you want with me, I'm just so happy I found you again," sighs Shell, somewhat calmed down (but still clinging tight to Sherlock).
"Let's get you home?" she offers softly.
And she can remember home, now, the palace (it was real), the world, the - heh, that crown she found in the nightstand was originally hers, wasn't it? - and she can remember Tony, and -
"But - but there are two of us."
She realizes only after she says it how that sounds, or how she guesses it would sound, to Bell-the-live-one. "I mean you are obviously the sane one you're in charge I'm not going to do anything you don't want but -"
"There could stop being two of us," Bell says. "I mean, we could - go back to being only one. But it would be complicated, and I want to think about it, and I want to think about it at home. And I know you want to see home."
"Sure," says Shell, "but I can't do anything about it. I can just torch, that's all. I've done it a million times and I go right on being me. Bell doesn't have to."
"This is what we'd have to think about," Bell says. "How to weight the two of us in a merger so the result wouldn't not like to be herself. Home?"
(Although it may be that Sherlock has to carry her for the party to go out the door.)
Out the door they go.
[Tony, you may want to meet who Sherlock urgently needed my help with.]
Bell supplies their location as the door closes behind them. "Tony's coming," she murmurs to Shell.
(But mostly Sherlock. The entirety of her body language the way she's curled up while Sherlock holds her says mostly Sherlock.)
"I died," says Shell. "The afterlife didn't let me go when Sherlock tried to get me. Now there's two. I didn't have a very nice time but I found her I found her I found her." (Sherlock's throat gets nuzzled.)
"We are considering ceasing to be two," Bell adds. "But it seems complicated to figure out how to not end up mostly her, when she's the one who by her own admission shouldn't've happened and she's got a longer history than me."
"Yeah," says Shell. If Sherlock puts her down now she won't wince, even.
