Jack Carter had been living and working in a little town called Eureka for a little over six years and while his evenings were generally quiet (and spent with his wife, Allison, and their children), his days were usually hectic as all get out. He was the sheriff in a town populated almost entirely by scientific geniuses (most of whom worked for an advanced research facility called Global Dynamics, which was responsible for the development of nearly all major technological breakthroughs since its inception). He also had the lowest IQ in the town (which did bother him from time to time, he'd begrudgingly admit).
Still, for a guy with the lowest IQ he was still able to determine (more often than not) how mysterious accidents came about, or how and why anyone would intentionally misuse technology. He's had experience with time and space anomalies as a result, which is why, when another intense white light appeared in Mar-Vell Memorial Park and a man literally face-planted and skidded across the ground, the first thing that came out of his mouth was: "Not again…"
With a grunt he rolled to his back to get a better sense of where he was, already grumbling about killing Fargo for using him as a test dummy, and his jaw literally dropped, not only at seeing the horde of zombies, but at the woman that he'd landed near, and the weapon she was using. He had to be dreaming. Had to be.
Still, when the zombies started to encroach on him he reacted immediately and hopped to his feet, pulling out his gun and squeezing off a few rounds. He really needed to stop watching Romero movies before bed. Emptying the clip, he reloaded and fired off a few more shots, moving around so as not to get trapped in any way. What he really needed was higher ground. Or to wake up. Waking up would be nice. When the clip emptied again, he reached for another one only to realize… "Oh, come on! This is the worst dream ever!"
He literally threw his empty gun at a zombie's head (which was both ineffective and a horribly stupid idea), then called out to Boss "I could use a little help here!" while pulling his baton out of a loop around his belt and using that to bludgeon the zombies with.
