Turns out that the woman on the roof of the van is the same woman who wanted to kiss Thomas back in the bowling alley.
Ah, gotta love reunions.
Lawrence eventually shakes the woman off of the van, and our heroes start driving to the boss's headquarters.
Lawrence shuts off the lights of the van to provide our heroes with a little stealth (even though it's dark and hard to see), and he guns the van so that they'll get there nice and quick.
Just as Thomas and Brenda are telling Lawrence to slow down or at least turn on the lights, the van jerks back and forth and comes to a stop.
Lawrence turns on the headlights, illuminating a bunch of Cranks blocking the road.
One Crank gestures that the van should drive past.
Hmm, it's probably not a wise decision to trust a group of Cranks.
