You’re staying at the Wheeler’s residence temporarily despite the silent treatment you and Mike have put each other through for the past 3 months. That’s when the power throughout Hawkins, Indiana is suddenly wiped out. The heater you’ve been using to stay warm in the basement during this frigid winter isn’t going to work with no power. Now . . Mike’s room is the warmer option but— maybe you should just face the cold in the basement.

Mike is aged up to 18.
