The marauders come up with a plan to get back at the Slytherins

The song at the beginning is 'Prettiest Star' from David Bowie's 'Aladdin Sane' album. Lyrics:

Cold fire, you've got everything but cold fire
You will be my rest and peace, child
I moved up to take a place
Near you

So tired, it's the sky that makes you feel tried
It's a trick to make you see wide
It can all but break your heart.
