So I believe that both the kids in Escape! and in Revival both would have been pretty short once they grew up. AKA their growth was most likely stunted.
They didn't eat much (if any) and they didn't really go anywhere outside of their little cells unless they had to cook. And in Revival after the failed escape the only time they went out was literally only to get tortured. With all of that and the fact that they had to heal themselves on a day to day basis with either the clothes and blankets they had or a simple med kit there was some serious medical problems afterwards.
Especially when they got captured for two years I would imagine that they didn't look their best. Depending on how long each kid was there it varies but yeah. Medical history ain't looking good.
Thank you for coming to my TED talk.
