Yes!

Instead of coming up from your roll you go over one more time as the tail goes flying by you again. You come up and fire off two more shots into the ugly white frog/scorpion thing.

The waitress - still lying helpless and naked in a pile of her own shredded clothes - tries to move, she's not making much progress with all the poison in her system but she's struggling.

The creature decides it will be better off closing the distance between you two. It leaps forward, claws extended. With time feeling like molasses around you, you leap backward, firing off two more shots that thud into the creature's large face. The claws slam into the pavement where you stood and cut deep gashes into the ground. Torn chunks of asphalt fly everywhere. The other hand swings heavily over you as you're reeling back and decide it best to fall to the ground, firing off another pair of shots.

One shot hits the creature in the eye. It straightens up, fully 10 feet tall. It screams again and reels back. You leap to your feet and keep firing more and more rounds. Blood pours from the beast but it still seems like it has some fight left...

It glares at you, standing there. Then it tilts to the side and slams into the ground, not moving.

You stand a moment, pistols aimed at it. Its skin goes clear again showing its insides. You stare, watching for any movement before you notice the things brain under its skull. The brain is scrambled and drooping down, pulverized by your bullet that pierced the thing's eye.

You slowly make your way around the creature to the girl, pistols still aimed at it a bit nervously.

When you get to the girl you holster your pistols finally, sure the creature is dead now.

You look down at the waitress, she is crying now. She tries to move but still can't quite do it. Now to decide what to do... You can finish the job, leaving the girl here (who knows, maybe she'll still be here anyways). You could also help her now and finish the job later, you have plenty of time after all... Though maybe your employer would be happier the sooner it got done.

Or maybe you could succumb to darker thoughts?
