For all the time I've know you
You've worn a mask upon your face
It appeared beautiful, perfect, and friendly
But now I realize that wasn't the case

For hiding underneath that mask
Was a soldier bent on destruction
Posing as a comrade fighting for good
But following the other side's instruction

You wormed your way into our ranks
And we accepted you as one of our own
But all of us were unaware
Your true intentions had not yet been shown

When an opportunity presented itself
You struck without any hesitation
Our troops started dropping left and right
Without any sign of infiltration

You knew you only had so long though
Before your actions got you caught
So you moved to abolish your final target
A tougher task than you had thought

That night, when you attacked me
You allowed your mask to fall
And as you fled, I caught a glance
Of the real person beneath it all

Well, "What doesn't **** you makes you stronger"
And you make me tougher every day
Which is why no matter what you do
I refuse to let you stand in my way

I learned some valuable lessons
About how you fight this war
And now those same old boring tactics
Won't work here any more

So thank you for the knife
That you embedded in my back
For you just gave me the tool I need
To defend against any future attack.
