"Ever wonder what it's like to drown?
Story of opposites.
There's peace, in water, like it's holding you. Whispering in low tones to let it in. And every problem in the world will fade away.
But then, there's this thing...in your head and it's raging. Lighting every nerve with madness.
To fight.
To survive.
And all the while this question lingers before you:
"Have you had enough?"
It's funny, you could pass a lifetime without ever having to face choice like that. But it changes you forever.
When your blood mixes with the filth and the river toxins eat through your nerves.
Oh, I hated you for what you'd done.
But as time passed...so did my hate.
And I was left with an understanding.
You see, the only way to defeat a superior enemy, is to stop at nothing. To become what they fear. 
And for that I thank you...
Old friend."
