She succeeds. Eventually.
She still talks in her sleep. The words still come without grammar, without correlation to any visible emotional state pervading her unconsciousness, without rhyme or reason.
The word selection is a bit different than Bell's.
"Dark. No - Voice. Someone. Hurts."
She has not had anything to wish to be awake for in many years.
She doesn't wake up during the nightmares. This has not been an effective strategy to make her experiences less nightmarish for many years.
"That's good." Shell seems very comforted by the fact that Sherlock can sleep with her in the room, still.
Shell has nothing at all to do. Bell can take care of the empire. Shell is accustomed to going for a very long time without eating or drinking. She can think of no reason to move at all for the next ever.
Well.
If they spend long enough like this, Sherlock is going to want to get up and cook.
Shell will only know this if Sherlock tells her. Shell cannot read Sherlock's mind right now. In fact, despite having asked for coins, the only one she's used is the one that torched her. She is simply no longer accustomed to being able to do anything worth doing at all besides progress through various stages between torch and next torch, let alone with magic.
She doesn't appear to make the connection that in order to make muffins from scratch, Sherlock will have to be unburdened by Shell.
Shell still has not conjured up enough inferential power to expect to be put down once they get there.
Oh, kisses, she's missed those, muffins are instantly abandoned as a possible use of her mouth in favor of lots and lots of enthusiastic whimpery kisses kisses kisses.
It is the highest priority. Shell has no idea how she managed to neglect this as an instant, first, essential step in Having Sherlock Again, but she is making up for lost time. Decades of it. She's sitting on the counter, so she can wrap her legs around Sherlock's middle, too.
