Quicksilver

They say that death is the only cure for lycanthropy.

We never learned much about Mrs. Lupin, did we?

Close your eyes, darling

Shut those heavy lids

Fringed with lace lashes

And ghostly freckles

On your white white cheeks

There's blood under your nails

Close your eyes, sweetheart

You've had a very busy night

And it is the dreaming time

Twixt moonset and dawnbreak

That this must be done

For you will wake momentarily

Close your eyes, little one

Rest and curl your tiny hands

Around the blankets I made once

Defile them with your precious

Hands that will claw and kill

'Ere you are much older

Close your eyes, darling

I'll promise this won't hurt much

A stab and a thrust

Of this shiny thing made just for you

And you will be dead to the world

As you were long since dead to me

Close your eyes, my son

For I shall kill you before morning
