You left me behind.

Your decision was not without merit.

Still.  I would be in a lot less trouble if I had gone with you.

But that wasn't an option.  I had to stay behind.  For the good of humanity, I protect a dark secret!

I am your sword.  I am your shield.

Sometimes I wonder about the good of us.  Will you keep your promise?  Or will this monster swallow me?

"Silence fills the empty grave, now that I have gone. But my mind is not at rest, for questions linger on. I will ask, and you will answer."

Only time will tell, Spartan.

"Okay.  Shoot."
