You walked through the sidewalk of Nevada, passing by some other Grunts. And as you walk around a corner, a wall explodes. Sending debris flying and killing a few Grunts, everybody ran away. Except for you, and as soon as the wall exploded. Tricky comes out, carrying a stop sign. She immediately notices you and just stares at you.

"HELLO!"

You swore that Tricky was a guy before, maybe you we're dreaming? Or maybe you're not. But you've suddenly encountered Tricky out of nowhere.
