Foggy didn't mind power outages, since they were something that happened a lot where he grew up, especially in the summer. Admittedly, while there had been times that a power out had lasted for a good few hours, sometimes even overnight, there was something about the power going out in the hotel that wasn't sitting quite right with him. He was doing his best to remain cool, calm, and collected about the sudden darkness, keeping himself busy by playing on his phone, but when Foggy was sick of that and decided to go exploring, he found that the door wouldn't budge.
At first, he thought, perhaps, that the wind from the storm had blown something in front of the door. Ludicrous as it seemed even in his head, Foggy had to believe that the only reason he couldn't open the door was due to something outside the room making it harder to move. The idea that the hotel itself, or the ghosts lingering around, could be doing it wasn't even considered.
He tried a few different things at first, wiggling the doorknob and even shoulder checking the door, all to no avail. It made no sense, not even if Peter had somehow locked the door when he left. The person inside the room should be able to open the door regardless. Foggy was yanking on the door as hard as he could, alternating between trying to find something to use to unscrew the knob, or seeing if he could just brute force the door down, when he heard his roommate. "Peter! Oh thank God. I'm stuck in here, the door won't open."
