The show host barely manages put ATHATHs arm into joint lock, but is struggling to hold it. Unfortunately ATHATH managed to sneak his pistol in. Not a big challenge, security didn't exactly check everybody they let it. So he pulls it out with his free hand and points at Ozarck as everybody else is moving in to kick his ass. This also means nothing is holding Ozarck in place so he's free to dodge despite of lethargy still slowing his mind.
Ozarck rolls of his seat dodging the bullet as ATHATH pulls trigger first time. However next two bullets make their way to their intented target. One bullet goes through his left arm leaving bleeding hole behind, but actually missing all major arteries by sheer luck. The second bullet however is not as nice; it hits into chest passing through the right lung. The pain and shock is enough to make Ozarck pass out.
"NOBODY MOVES!" ATHATH shouts. "MR. WHITE HAS TEN SECONDS TO SHOW HIMSELF AND GET DOWN HERE BEFORE I START TAKING POTSHOTS AT THE CROWD!" He continues, completely oblivous to the fact that it is Mr. White who's twisting his other arm hard. By now ATHATH's religious fervor is starting to fade.
Beirus hesitates to aproach armed man who's threatening with random shootings, but NAV is not held back by such limitations. (Your gun was unfortunately confiscated by security). He charges at clearly dangerous man, willing to danger his own life. By employing erratic evasive movement NAV closes in and delivers a kick at ATHATH's pistol arm. It is not enough to make him drop the gun, but most certainly enough to throw aim off towards ceiling.
Two men in security uniform runs from the lobby, batons and tazers ready...
Rest of the audience is too shocked to react.
