A/N: Hey! So I was listening to this song while I worked on Marauders' Dawn and it inspired me for this fic. Hope you like it! The song is 'Monster' by Skillet, check it out. ;)

Disclaimer: I do not own Remus, the song only Catie.

The secret side of me, I never let you see
I keep it caged but I can't control it
So stay away from me, the beast is ugly
I feel the rage and I just can't hold it

It was that time once again; Remus could feel the monster within.

It's scratching on the walls, in the closet, in the halls
It comes awake and I can't control it
Hiding under the bed, in my body, in my head
Why won't somebody come and save me from this, make it end?

Catie wanted to help, she had showed him several potions that would help him keep in control when he transformed, but he could still feel the monster just beneath his skin.

I feel it deep within, it's just beneath the skin
I must confess that I feel like a monster
I hate what I've become, the nightmare's just begun
I must confess that I feel like a monster

He was a monster, the nightmare had begun, and Remus only hoped that Catie wasn't near.

I, I feel like a monster
I, I feel like a monster

He kept his secret hidden from everyone, except his closest friends. He kept it caged but he sometimes he couldn't control the impulses. It tore him up inside, when he had hurt Catie, who had tried to save him from the monster

My secret side I keep hid under lock and key
I keep it caged but I can't control it
'Cause if I let him out he'll tear me up, break me down
Why won't somebody come and save me from this, make it end?

No matter what he did he felt the monster always underneath his skin, Remus loathed what he had become as the nightmare began again. He admitted to himself that he felt like a monster.

I feel it deep within, it's just beneath the skin
I must confess that I feel like a monster
I hate what I've become, the nightmare's just begun
I must confess that I feel like a monster

I feel it deep within, it's just beneath the skin
I must confess that I feel like a monster
I, I feel like a monster
I, I feel like a monster

One night when he lay in bed he felt it somewhere near, it was then he realized the monster inside him wanted his soul, his heart, his Catie. No one could hear him scream he hoped it was just a dream. Someone had to stop this monster, because he couldn't.

It's hiding in the dark, it's teeth are razor sharp
There's no escape for me, it wants my soul, it wants my heart
No one can hear me scream, maybe it's just a dream
Maybe it's inside of me, stop this monster

I feel it deep within, it's just beneath the skin
I must confess that I feel like a monster
I hate what I've become, the nightmare's just begun
I must confess that I feel like a monster

When the nightmare begins, he loses all control and watches as scenes play before him and the monster took over.

I feel it deep within, it's just beneath the skin
I must confess that I feel like a monster
I've gotta lose control, he something radical
I must confess that I feel like a monster

Catie told him he wasn't a monster, told him she loved him. But Remus pushed her away; he felt like a monster, he was a monster.

I, I feel like a monster
I, I feel like a monster
I, I feel like a monster
I, I feel like a monster

She finally convinced him, he wasn't a monster, and once he admitted that the monster crept away into the back of his mind, only to be unleashed on the full moon.

A/N: So what did you think? Oh and take a breather Catie-fans she won't get hurt physically but inside her where her heart is. ;)
