Imagine getting a new apartment for the first time and you get very excited. Before getting all your things out, you put on music and start dancing. When you grow hot, you start taking your clothes off until you’re just in your underwear - when suddenly you hear a knock on the door. Imagine that before you can dress, Loki barges in.
