It takes five hours to pack up everyone, get to the airport, board the plane, get off the plane, get home, unpack everything. Five hours latter and Jack's back in his room. He collapses onto his bed, exhaustion from the past few weeks consuming him, dragging him to sleep. He finds his mind streaching a single thought out to her, 'Honey, I'm home.'
He's fast asleep before he can hear her answer or not.
It's dark when he opens his eyes again to the sound of someone moving quietly about. So quietly that it's weird that we woke up at all because of it. Then the moving stops before he hears something, or actually a few somethings softly tapping against his window. Then he hears what really woke him up, 'How can he sleep at a time like this. I rush back home and he's just sleeping there.'
