The birth of a werewolf

-- I want to show you the moon.

-- Why? I have seen the moon.

-- I want to show you the moon that will haunt you on your best days and call you on your worst days.

Remus looked at Patronus intently.

-- How old are you, Remus?

-- I am going to be fifteen in a month.

-- Nice age... A lot of things can happen at this age... Have you been dreaming lately, Remus?

-- Yes.

-- What have you seen in these dreams?

-- I have seen a beast. A monster running beside me, devouring me.

-- Remember these dreams, Remus. They are prophetic.

-- They mean I will be killed by a monster?

-- No. But the reality sometimes will make you wish you were. I want to show you the moon that will make these dreams a reality.

Outside it was dark and chilly. They went out on the porch.

-- Look at the moon, Remus. What can you tell?

-- It's full.

-- Look at it, look at it hard. Remember this moon, for next month, it's going to change the shape.
