As Greg goes back Casey bolts forward instinctively, putting himself between the shadow and Greg and swinging his bat at what might be the creature's head.

"Get outta here! I got this!" Greg has to get out of here, because Casey's about to try the fire thing again and who knows what he'll catch this time. The bat, hopefully. He's going to try for the bat.

How is he gonna do it without catching everything on fire...Rub it between his hands like a campfire stick?
