Azrael was walking around the house, cleaning and throwing out junk, he was the youngest of the three cousins.
Azrael: Lucifer! What is this!!?!
Azrael was holding a bag of McDonald's, but he didn't know much about the human world.
Lucifer was sleeping a chair almost twice the size, and nothing will wake him up, not even an earthquake.
Gabriel was cooking some eggs for breakfast and alongside with some coffee for Lucifer.
Gabriel: Azrael! Wake up Lucifer, time for breakfast!
Azrael: One question! How?!
Lucifer: No need to! The smell of eggs woke me up!
As Lucifer got up from his chair, each step was very heavy, Azrael followed behind.
Lucifer sat down and so did Azrael, Gabriel brought Azrael eggs and coffee for Lucifer, then got himself some eggs too.
Gabriel was a sort of middle aged cousin, certainly older than Azrael, but Lucifer was the oldest, and almost twice the height and size.
Azrael: Where did you learn to cook?
Gabriel: I just like to cook
Lucifer: Gabriel, there's some mail you need to deliver, get on your human form and go send it, after all aren't you... Gabriel The Messanger?
Gabriel looked at Lucifer with tired and annoyed eyes, then walked to his room where he got dressed for his work.
As he walked out of house...
Gabriel: And aren't you... Lucifer the Fallen Angel?
