Nice job showing L&C's POV at the kidnapping of their daughter. (I'm glad you left out the frantic disbelief and the dread part and moved right on to the "we're going to solve this" part.)
I agree that Henderson knows more than he lets on. He's no dummy.
The scary thing - does the kidnapper(s) know that CK=SM and hence the kids can be affected by kryptonite?
