Although Jack can pick up on the change in Ma's tone of voice, he doesn't understand why she sounds this way. She's been trapped inside Room for eight years, with nowhere else to go. Not a day goes by without her wishing she was out of there.

Mouse is the first living thing from Outside Room that Jack has ever seen, and he regards it like he regards everything: with wide-eyed child-like reverence.

Once Jack finds himself Outside Room, he is kind of like Meltedy Spoon… he's not the same as anyone else. Although a lot of people like him because of his differences, they also want to make him a part of society. But taking Room out of Jack would be like unmelting the spoon.
