HA! fighting back. That's right. LOVE IT!
But hey, on a lighter note, it'd be funny though if like the people who opened the door (the good guys) opened it to another group who was doing the same thing they were doing, but just on the other side of it.
"Hey, what are you doing here?
"We're the Defenders. What're you doing here?"
"No you're not. We're the defenders."
"No you're not, we are!"
*fight ensues*
