Then there will be nothing to distract her from her own incompetence. She wishes she'd paid more attention to, like, Oregon Trail memoirs, or how the kid does things in My Side Of The Mountain, or asked someone at superhero camp survival class about this situation, or something.
She eats as much as she can, and gives Wishbone as much as he wants, which is a lot for someone so small, honestly. She's not super sure how turning moose-thing meat into moose-thing jerky works, and isn't even sure she has a good enough idea how to do it to take a stab in the right direction, but she figures she's gotta try to make good use of what she has. She cuts some strips of moose-thing hide and uses them to hang some meat from a tree, then starts a second fire underneath it, aiming for something low and slow-burning. Maybe this'll cause dehydration. Maybe it'll ruin everything. Who knows.
Aiming to make a wooden rack to hold stuff high over a fire is a lot more frustrating. Stuff keeps breaking or falling apart as she works on it. She's not exactly afraid of dying in the next little while here, but she feels pretty stupid.
She does manage to keep her moose-thing hide pretty close to whole in the process of removing it from the animal. She scrapes it off pretty well, but she's not sure how to tan it, and it'll probably start rotting at some point if it doesn't get preserved somehow. Maybe someone in town will know what to do with it, if she can get that far before her stuff rots.
She works late into the night without feeling like anything she's doing has been unambiguously a good idea. At least she can have more meat for dinner. Could be worse. Theoretically.
(She misses Alex. Alex would know what to do with the moose-thing.)
In the morning she eats some now-slightly-suspicious cooked meat, packs up the scraped moose hide and teeth and a few bones and some suspicious-looking not-really-much-like-proper-jerky stuff, puts on some non-bloodstained clothes, and heads out. Be cool if she could keep the antlers, but they're big and hard to carry, and she has bigger problems. She leaves the rest of the body behind and sets the fastest pace she can sustainably manage. (This is pretty fast. The main limiting factor is the forest getting in the way, so she can't hit her normal running speeds.)
