Tetsu
Tetsu will (logically) commit the verse to memory. He will then set about doing what work he can around the place before nightfall. It should get dark pretty early this far north and up in the mountains. As he works, he'll also gather what herbs, fungi, etc. he'll need to cook a decent dinner. When he gets too tired to work any more, and when there's an appropriate amount of time before dinner, he'll again knock on the door and renew his offer to cook for her -- he'll have to use some of the supplies from her larder, of course, as he's not hunted and has no idea as to her tastes.
Tetsu rolls 1d20+4, getting [16,4] = (20) for Cooking Roll.
