That is totally normal, when looking at other long term hostages. Jaycee Dugard, Shawn Hornbeck, Elizabeth Smart, the 3 girls in Cleveland, ALL OF THEM were slowly, over time, given small amounts of freedom. That's how the brainwashing process works.
The children are frightened for their lives, chained up, tied up, locked in closets, kept solitary, in the dark for hours and days on end---stressed, intimidated, controlled, treated like prisoners, and they shut down totally, become like emotional zombies.
Then slowly, their captors begin to do one or two very small 'favors.' They unshackle the chain, and allow them to be tied to a long rope, so they can walk a few feet.
Or they are allowed to come up into the main room, and eat some soup. It is like a dream come true. They have not been killed, or maimed, so they feel thankful to their captors, and they try not to anger them, so they do not have to go back into the dark closet....
