Is Jack still trapped in the room?

    One thing that I noticed in last night's reading was a sense that Jack was still living in Room. This idea is supported by small details in the text. For example, on page 208, when Dr. Clay sees Jack drawing a picture, Jack explains to him that there are walls around the spaceship. It seems like just a passing detail, all Jack says is "Walls" when Clay asks him what is around the rocket. I'm surprised that there wasn't a scene of Clay talking to Ma about these walls afterward, although this is Jack's narration, so maybe there did talk, but Jack didn't overhear anything. The biggest issue with these walls would probably be why Jack decided to include them in the picture. It's not as if Jack ever saw a rocket (TV excluded) inside Room, making this the only place he can picture one. He just decides to arbitrarily draw walls around something in a picture. Perhaps he thinks there's something different about the rocket (having only seen it on TV) that doesn't allow it to be placed in a picture with other "real" things, such as Ma and Nick.
    Further complicating the issue with Jack's rehabilitation to the world is his opinion on going outside. I would assume that, for someone who has only seen pictures of trees and parks and other kids for their whole life, they would want to go and experience these things that they saw. Now that Jack has this opportunity, he seems reluctant to take advantage of it. Instead, Jack seems almost ambivalent to the outside and expresses little interest in going there. This is evidenced by Ma's quote on page 210, "If we stay indoors all the time, it's like we never did our Great Escape at all." Later on, when Jack is in the van going the dentist, he doesn't seem to acknowledge that he is actually outside. Yes, he says that "we're actually driving outside the big gates to the rest of the world" (222). But Jack says "rest of the world," not outside. This seems to create a distinction between the outside world and actually walking outside in Jack's mind. It seems odd, yet given the 100 or so pages left in the book, I believe that this issue will come to pass or be resolved.
