Jack is starting to realize that the people Ma is related to are his family too, whether he wants them to be or not. He also understands that just because they're family doesn't mean that they like him… and vice-versa.

Grandma is really broadening Jack's horizons now by showing him the globe. It seems that Jack's world grows bigger and bigger every day. This is the first time he has realized (even though he doesn't quite get it yet) that where he is right now barely registers on the globe.

Note that Jack calls Grandma's home "the house" at first. He doesn't call it home because he doesn't yet feel comfortable there.

This is a good question. Ma calls her new apartment "home" mostly out of a hope that it will be. Jack understands, at five, that they will have to make it a home; it doesn't come ready-made that way.

When Jack transitions from Room to the Clinic, he feels like he's part of the real world. He's still separated from society in a way, though. He's still protected inside the Clinic, but in the real world, everyone gets hurt at some point. Dr. Clay still wants to protect Jack from sunburns and bee stings, but Grandma thinks that's just a way of life. Who is right?

Good question, Jack. We don't quite understand it either. It seems that the more obligations you have, the less time you have to do them in, whether it's a job, family, or being home for the latest episode of So You Think You Can Dance.

After Jack spends time apart from Ma, she is unable to breastfeed him. But the time spent apart also makes Jack realize that he doesn't need to be breastfed anymore. Maybe time apart from each other is healthy for Ma and Jack, after all.
