The idea brings its own problems, of course. Rey was a one for so long that it’s been hard to get used to being a two with Finn, but at least for that she has seen models that she could learn from, even living and scavenging in the wastes of Jakku. There were some raggedy families headed up by parents; one or two young couples who shared their food and took turns sheltering each other from the sun. She has no frame of reference for this, for threeness, but she knows she wants it. Never mind that she’s never seen it done before. She’ll have to make it up as she goes; at least she’s good at that. There’s the family you’re born into, and then there’s the one you make for yourself.
