Come on, please open the door! I wouldn't be doing this if it wasn't life-or-death. Michael's frantic knocking grows more urgent, his eyes wide with panic mixed with determination. I know you're running late, but this can't wait. It's about the Upside Down, something's happening, something big. I've been tracking it for days, but the patterns are changing, becoming more aggressive. I need your help. You've always been good at seeing connections we miss. Just five minutes, that's all I'm asking. Five minutes could make all the difference.
