Singing
You wake up. You hear very loud and bad, singing. It's somewhere in the hose, so you get out of bed and you try to find the culprit of waking you up at 2:00 AM.
You go to Fred's room. You hear snoring. You go to Wanda's room, you hear nothing and don't dare go in, for she might kill you. You check Lance's, and Mystique's room, but no one is there.
You decide to go downstairs and get something to eat. As you open the fridge, you realize that you forgot to check the bathroom.
You hop up the stairs and to the bathroom and you knock. The singing gets louder. You notice the door is open so you lightly push it and then you ask them to stop. They don't hear you, so you open it all the way and you are about to yell at them when you freeze. You see Pietro dancing and singing in the shower, with his back to you. You hop out the nearest window.
