Kimi isn't sure what Jack is asking her. She puts the doll in front of her face and tells him that Anaba is her big sister. Then she takes his hand and runs after the older girls. She's hoping they let her come play with them since she has Jack in toe. It's a mutual usefulness, their relationship. On the way she uses the doll to ask him if he's going to stay forever and marry her sister. Because if not she would like Jack to marry her instead. She's prepared to wait.
The adults glance at them as they run off, shaking their heads. Jack has been accepted by the old matron and he's now officially part of their tribe. He's not expected to do anything since he's so obviously stupid but at least quiet little Kimi has a friend now.
