So the kids have awakened and, looking out they see the hurricane blowing outside their window. They realize everything is dark and it seems there are no lights-and no power. They remember what mom and dad said the night before: there might be a black out due to the storm. They are all staying home to take care of them and they need not be scared.
This scene would have some kind of dialogue going between the two kids, recalling what their parents said, weighing their observation outside the window, and putting together some guesses of what would be outside the door in that scary part of the rest of the house which they have not explored yet(since everything is all dark and they aren’t sure where their mom and dad are). If done right, if I get it right, the child reader is supposed to ride along this moment when the kids take a brave decision to not just sit idly and wait ( I mean, kids would never sit and wait anyway), not cry and despair, but to take action; to gear up and recall the plans set previously with their parents; and to execute that plan.
