Unfortunate Children
About the rest of the missing children, some of them would be searched and get back with their families in a few months. Others would be searched and might be found in a year or two. But unfortunately, the rest of them remain missing.
Rest of the Children
The last case of the missing children is never found again. Rarely, they will ever come back after being missing for such a long time, just like Crystal. When they return everyone expects it to be the happy ending but that is not always true.
