She smirks at him, letting him go on and tell her the great beast he's been looking for these past weeks. When he does tell her she seems confused. She's interested in the map because it never occurred to her to make pictures of land (that doesn't look anything like land and she wouldn't know what Jack was drawing if she wasn't sitting there while he studied a rock formation or shoreline and then sketched it out). It's like a game. She peers over his shoulder trying to figure out what all the other symbols are. But 'life water'?
Slowly she starts to laugh at him. The same kind she did when he first appeared kissing hands. Jack is being silly and weird again. She thinks the old lady that took Jack in told him about the water and he bought it hook line and sinker. Poor thing. "Aiyana play game with Jack. Story. Life water story for children." She kisses his temple.
