Daz looks confused about the fish burial but obviously can't ask.

Margaret doesn't know how to mime the concept of fertilizer, but she points at the plants and mimes them getting bigger. 

Shrug.

Likewise shrug.

The next days and weeks see the development of something of a routine. Margaret catches and cooks more fish; the crops of peanuts and various berries take to the local soil acceptably and start supplementing her arms as a food source; the three of them deliberately keep their sleep schedules out of sync.

After Sovi and Daz have observed her farming-related behavior for a couple of weeks, Margaret will discover a fourth person, hard at work in the garden, when she wakes up.

Margaret's been bugging Sovi for a few words of the local language now and then, but she's sufficiently surprised and still-waking-up that she ends up saying "Hello?" in English.

"Hello," says the new person, who appears to be a woman. (Sovi and Daz are asleep cuddled up under a tree.) "I'm Kiray."

"Oh, you do speak English! I'm Margaret. Are you, um, new? Or another stranded Earthling?"

"I'm new. Sovi made me."

"Ah. Well, pleased to meet you. Thanks for helping with the garden. Um, tell me about yourself?"

"I'm here to help with the garden."

"So are you inherently really good at gardening, then? I'm still not totally clear on how this works."

"I'm as good at gardening as Sovi could make me."

"Can you teach me stuff?"

"I can try, but I'm not sure how much you know."

"I'm mostly guessing. I know that plants need water and sunlight and nutrients in the soil, and that rotting stuff can provide the nutrients, and that it's a good idea to rotate which crops you grow in a given field from year to year."

"I know those things and a few more. You can work with me if you like."

"Great. I between us we can figure out a lot of stuff." 

She resumes de-rocking the ground around some of the plants. "Why didn't you make a gardener yourself?"

"I've never made anybody and I'm worried I'd do it wrong. That I'd make a person and they'd be unhappy, or sick somehow, or wish I had made them differently."

"Oh. Sovi's never made a person either before me."

"Sure, but she was made herself and probably understands it better than I do. I guess if she did a really good job maybe it's easier than it looks?"

"I seem all right so far."

"You do! You seem like a really cool person. Which might mean it's easy or might mean it's a good thing Sovi made you instead of me." Shrug.
