In the weeks after their escape Bonesaw is hard at work, building up a lab and growing food and splitting branches and stitching them into a scaffold so that they grow into a living treehouse.
Weird, Bonesaw isn't even touching Beka.
Search search search.
"Huh."
"I think I figured out what it is but I have no idea what's even causing her body to irritate her nerves like that - I can still fix it by making it so the thing stops being painful but I'll need to add some extra nerves to compensate so she can feel other things like normal."
Bonesaw grabs a bit of Beka and starts stripping her skin to get at the nerves.
"Yeah, I'm only shaving some so the regrowth agent will make sure it's all back and working in a day or so, it's just harder to do that for a baby since they don't have as many nerves to start with."
Shave, twist into a baby nerve, and repeat! It's almost soothing.
Beka holds still and closes her eyes and reads Kat's mind to remind herself that it doesn't hurt her a bit.
And then soon enough it's all done!
"Done! She'll shed her skin in a few hours and the scars will disappear then."
She can flip the normal sensation back on for Kat now!
"Yeah, to help with the shedding. I can't change that... Oh hm. Unless I make her sorta a lizard..."
Bonesaw puts down her tools and hopefully waits for Beka to tell her she did a good job.
Scritch scritch scritch. Kat squirms in her arms. "She's not in pain," she reports, "probably when she's done itching she'll be all better."
Beka wears Kat around most of the time, usually on her back once she's big enough to hold up her head. She paints the treehouse, and walks on water to get to the best fishing spots, and collects nuts and berries and roots and eggs and animals for Bonesaw to render into whatever combination of dinner or materials suit her. Sometimes she comes up with project ideas in case they'll be distracting - Elves sometimes ride horses, what if this deer were rendered suitable for riding, it could have its own stirrups built in? What if these plants were even more responsive to the crop song than regular plants? Once there's a Lucky Charms production setup could they be introduced to other foods from Bonesaw's home too?
The deer idea sounds great and Bonesaw can make them go so fast and easy to ride! And she can give them really pretty and detailed antlers that branch in a fractal-like patterrn recursively so that you can't even see the smallest branches with the naked eye and also they are razor sharp as a side-effect of this.
The crops things is complicated and interesting and soon enough Bonesaw has figured out how to grow most vegetables in minutes with the song and some other hypergrowth modifications. She has to make some changes to Beka and Kat's digestive systems so the foods safe but that's easily done.
The Lucky Charms set-up is an ongoing long term project that she's going to keep spending a little bit of time on but not that much. She can definitely make mac'n'cheese for dinner one night! And for dessert there are intricate lollipops that take on the shape of iridescent shells a sea creature might live in.
The lollipops are so beautiful!! If Beka catches snails for her can she do real shells like that to hang from the treehouse?
And soon enough there place will be lit by iridiscently glowing snail shell creations on strings, the light dimming in the evenings.
Beka experiments with several ways of arranging them for maximum effect. There's not a ton of string to be had in the range between "animal gut" and "rope" but it turns out braiding grass into rope is kind of fun too.
One night Bonesaw smells blood - her own. She's wide awake near instantly and flips herself into a crouch, adrenaline shooting into her veins as she scans for who's attacking her but none of her senses are showing anything and she can't see what to attack and -
"BEKA!!"
