Shell doesn't know how long it's been. She doesn't know where she is. She doesn't know how to get home, or if she has one.
She stands on Voice's doorstep. She blinks slowly at the brightness.
She walks in a random direction.
Downsiders aren't big on charity. It's not like it's going to kill her if she doesn't get help. It's not like she's unfamiliar with the effects of dehydration and hunger; Voice didn't always remember to take good care of the pet in the basement. Shell walks, and when she's tired she lies down on the ground and sleeps, and when she wakes up she walks, and every few days she curls up on the ground, waits to torch from thirst, and then gets up and goes on.
She doesn't count the number of times this happens. It doesn't matter.
She walks. She has nightmares. She walks.
On an unremarkable day on an unremarkable street after unremarkable stretches of years, she feels herself cross a telltale threshold of dizziness and headache: she cannot make significant forward progress towards Not Where She Is Currently Located until she torches or (less likely) someone gives her a lot of water. It's possible she'll be able to sleep through this torch. She sits. She leans on a wall. She should probably pick up the next sharp object she finds. Maybe a piece of broken glass will present itself. Then she can skip these parts.
She sits, and she closes her eyes, and she waits. If the buildings around her would ever have seemed familiar, they don't now.
Shell, who cannot see Bell from where she's sitting, draws her knees up to her chin and hugs her legs.
"...Another alt is an emergency? Or do I just need to read the story directly because words have failed you?"
Shell doesn't look up from her knees at the sound of Bell's voice. (Like all voices, they sound different from the inside as opposed to the outside; she doesn't even recognize the sound.) She is berating herself for misjudging her leeway with Important Sherlock.
Words have more than failed her. Everything has failed her. This is Bell but it's not Bell but it is and she is hurting and Sherlock does not know how to fix it how does she fix it what do they do.
"Oh, shit," she murmurs. "Oh shit oh shit oh shit."
And she drops her hand and she takes five long steps in Shell's direction and she cups Shell's face in her hands. "Hi, Shell," she says softly. "Do you want to remember?"
"I said this morning, if nice things happened to me, that would be a nice thing I'd want, a really good memory - but - but I think I upset Sherlock, and she's very important -"
She spends a hex.
Shell flinches as though she's been electrocuted, and her eyes fly wide open and then squeeze shut.
"Do you need a minute?" Bell murmurs to her counterpart. "I think you've got more memories to process than I did."
Bell takes that minute to go over to Sherlock and steer her in Shell's direction. [You don't have to react any special way. It's you she wants, not somebody following some script. But be there,] she says to Sherlock.
"I forgot you," she says, weeping. "I forgot you. How could I do that? I tried - I really tried - I kept you longest of anything - but I forgot you, I didn't even recognize your name when Strat said it -"
She finds the mental equivalent of wordless screaming.
[It's okay. It'll be okay. We'll figure out what to do with her, she'll be fine, it'll be okay, she doesn't blame you - I didn't think to look for anything like this either, it's not your fault.]
"I love you," Shell sobs into Sherlock's shoulder. "I love you, I love you, do you still love me, please still love me - I'm so sorry I forgot you -"
(it is her fault it can't not be her fault it will always be her fault she is wrong she is of no more than practical value and whatever practical value she has was insufficient to stop this from happening)
She does not uncling. She clingsclingsclingsclings.
"I used to wish you were there, it was terrible and I did it anyway, if you were there it would've meant you were dead, I'm sorry, I love you I love you."
Bell moves to sit at the table Shell and Sherlock are both sitting on. [It is not your fault. I didn't think of this either, I was in just as good a position to do so as you were, I could have scanned the memory of the wish for loopholes and I didn't, I could have wondered about the details of how resurrection works and I didn't, you and I did the same thing, we looked at me being alive and never hypothesized that somewhere Shell was being dead, is it my fault?]
"No, no, you're alive, it's good that you're alive, I'm glad you're alive, and I found you, I found you, you're here, I love you," says Shell, crying again. "I figured out what happened right away before everything - my guide took one look at my apartment and thought you'd be a suicide but I knew better - I knew you'd bring me back and that was why it was little and I knew you'd be okay and Tony would be okay and Atlantis would be okay and that was all good but I'm just so selfish -"
"Everyone at home is fine," Bell confirms softly. "Ranae and Shark never even found out. Tony did but only after I was alive. Coin and her helpers are all on the moon. Everything's just how you would've made it. I'm so sorry for never imagining you."
"I -" Shell hiccups between sobs - "I never would've imagined me either. There's no way but through here to do anything to communicate with livelings - before I forgot everything I was going to see if there was a - a biography of you or something in the library - but I never did - and now I'm here and - and now what?"
