I get what you're saying, but in that particular location, he would have other options, and IMO, most kids would have taken those options by this point. (After all, 7 weeks is a long time for actual, adult survivalists who know what they're doing to stay out in the woods by themselves!) And this isn't some isolated, inaccessible place hours from civilization. Even in the most out-of-the-way parts of the forest, it's probably less than five miles from a highway and maybe ten miles from the nearest town. There's campsites and emergency phones in the park as well. A kid with those options isn't just going to sit in the woods and slowly starve when he knows he can just walk out of there at any time.
IMO. MOO. IANAS. (I am not a survivalist)
