He wanted so much to be brave,

but he wasn't brave, he was breaking.

Knowing it had been Peter, knowing the rat

had betrayed them all,

but it was his fault,

he'd been the one urging, pressing,

whispering in James' ear.

He'd said he was too obvious,

he'd convinced them to change at the last minute!

It was his fault they were dead.

If only he'd been braver,

if only he'd realized before that Peter

was really the enemy,

but how could you know,

how could you ever believe one of your

best friends was nothing more than a rat?

It didn't matter, he was gone now.

He'd killed him, he deserved to be

behind these bars,

he deserved to never feel joy

happiness again.

If only he'd been stronger,

if only he hadn't been afraid,

he should have been there.

He should have trusted himself,

trusted James, trusted Lily

and now, now they were gone.

The wind whipped outside his cell.

The chill never ended, nestling in his bones.

Shifting back to Padfoot helped

the fur was warmer, the mind was

less complex.

As a dog he wasn't a coward, he was just a

creature, just an animal.

Part of him dreamed of losing himself,

losing his humanity to the animal.

Then he wouldn't hurt,

then he wouldn't feel the guilt

eating him alive.

The fluttering of the newspaper

caught his attention.

He'd never cared about the news.

It was all bad, it was all a reminder

of what he'd lost, the world

he'd left behind in his moment

of cowardice.

The smiling faces on the front page.

The rat...the rat...the rat...

missing a toe!

Peter was alive!

Peter was alive!

He hadn't killed him,

he needed to get out of here,

the truth was right there,

printed right there!

Peter would pay for his betrayal,

Sirius was going to make sure of it this time,

this time the rat wasn't going to get away,

this time, he would kill him!

He'd already served his sentence

he'd already lost so much of his own humanity

now was the time for revenge,

now was the time to avenge James and Lily.

Padfoot slipped under their radar,

they were watching for people,

not underfed, scrawny mutts with matted fur,

Peter was at Hogwarts, with the boy in the photograph

Peter was with Harry.

Sirius smiled for the first time in what seemed like forever.

Harry, he'd finally see Harry again,

and this time, this time,

Peter would die and Harry would be

safe with him.
