Sandy tries taking everyone in once they're introduced.  Stephanie, Eric, Jack, Rachel...and Virginia.  Of course once they spot movement she shakes her head. "No wait!  It could be something..." And then there's stuff all in the street and there's the biggest damn crab she's ever seen.  Her only comfort is that it's not solid black with glowing red eyes.  If that creep came back there'd be hell to pay.  Of course she has no idea if that man is the threat or if it's his dog, or if either one of them was really real.  And it's not the time or the place to be thinking of such things.  Unlike Jack, she turns grabs under the support of the car then aims to pivot and swing the car into the crab.  Though once she sees Jack's plan her own plan takes a much shallower throw, hoping to get the car-made-weapon into the legs of the creature.  They won't have much to worry about if the thing doesn't have legs!  She also doesn't let go of the car aiming just to bash the legs nearest her until they break.  Or maybe she'll pin it.  Whatever.  Her mind is really more on 'Holy shit a giant fucking crab!  Smash it!'
