Kaitiaki doesn't want to mess around with the berries while Damisa is around, so she spearfishes without the handicap while he drinks the fresh water and watches. (He tries wading in deeper, but the cold water on his still-healing wounds does not agree with him, so he returns to the shore.)
She tosses him a few freshly-skewered fish; he snaps them out of the air with delight. It's a delightful way to spend a few hours, and quickly becomes their morning ritual - they stay until he's full enough to start napping at the riverside and she's gotten enough extra fish for his dinner and her lunch.
Then they head back to their campsite (Kait grabbing branches and sticks on the way), where he happily sleeps by her side for several hours while she tends to fire and cuts notches in the long branches as needed for the shelter. (It's going to have to be bigger than she originally planned; it needs to fit both her and Damisa, who's still growing, as far as Kait can tell).
Once he wakes up and she's eaten lunch, they go foraging/hunting/exploring. He mostly watches, at first, but after a few days he starts using his nose to help, nuzzling Kait when he's caught the scent of berries or small game.
She loses count of how many days pass like this. It seems less important than the material changes each day brings: her shelter (nearing completion), her food stores (increasing as she stockpiles the river tubers), and her best friend (no longer limping or wincing, now starting to fish for himself).
