Doug
A parent's job is to protect their kid.
At a certain point, though, there's only so much you can do. Give 'em a helmet and kneepads, they still might skin their knee. All of life's like that, on a grander scale.
Maybe your daughter almost gets abducted by aliens, for example.
Doug feels guilty about that. Wishes he'd seen the signs, gone to the authorities, protected all the kids. But that won't help, so he tries not to dwell.
Maybe Connie will get Steven back, and it'll all be okay.
But if not...
Just in case, Doug researches grief counseling.
