"Thanks! The statistics are at least encouraging that one of the three of us will get something workable. I hope it's me, but I could work with it being Sherlock or Tony."
(She doesn't specify what they and their alternates are doing.)
"That's fine," chirps Bell. "More than fine. I'm so glad I found you."
Bell reads more of the manual, after the part with the helpful graphs. She's a little less manic about it now that she is floating.
When Matilda said she wrote three papers on it, she apparently meant more like thirty. Unless only a few of these count as papers the way she meant. She's credited as an author in every single document that credits authors.
Also, for some reason a disproportionate focus has been given to the subject of conjuring food.
She reads all of it.
If it seems like Matilda is open to being talked to, she makes remarks about it as she goes, but she is also open to just... reading. About magic. This is the most technical magic description she's ever gotten her hands on. (Reading about any other system has always seemed needlessly tortuous. She couldn't have them.)
She is absolutely a magic nerd.
(And she's going to stash the new computers in her room, just in case, because sometimes fucking Milliways earns its name.)
"Well, if that happens, we can leave each other notes at the bar and try to catch each other again? I'll be here more frequently than I used to. Tony can sometimes summon the door and Sherlock runs across it more often than I do. Anyway, I'll try not to take six hours!" She scoops up the laptops, stashes them, and goes Stark-hunting.
They are all snuggling. The Tonies are discussing technology.
"I found someone with contagious magic," Bell says loudly and without preamble.
"Downstairs. She's called Matilda. I met her when I was six and then never found her again. She has to do magic to whoever she's trying to be contagious at. Come on, come on!" Bell can't contain herself; she races down the hallway to the stairs again.
Bell finds Matilda again, and on the way down the stairs, she chatters: "And she can conjure stuff out of thin air - I got us laptop computers, and extras for Tony to take apart - and her magic system can do just about anything if you understand it well enough and the contagiousness thing doesn't work perfectly but the odds are good it'll work on at least one of us, and," breath, "there she is! Matilda, this is Sherlock! Sherlock, Matilda!"
