When Kate thought the party needed some excitement she was thinking a band or DJ, not armed assailants that weren't quite human. Compared to Killer Croc and Clayface, these guys were something else. They looked cold, emotionless, soulless. They didn't ask for money or make a grand political statement, they just killed with frozen hearts. Kate didn't bring a batarang or anything of that nature, carrying that stuff on her person is just asking to be caught red handed. Basically, she brought a whole lot of nothing to a gun fight. Usually Kate wouldn't be one to stray from a fight, but as stubborn as she is she isn't dumb enough to charge at a guy with an assault rifle; at least not without the cover of night and a mask. Apparently her grandma had the same idea as she sprang out of there like a jackrabbit, looks like those aqua pilates classes paid off. Kate had the same idea of living to fight another day, except there were some brave and bold and brainless heroes who thought they'd stop the bullets with their fists. Great, now she had to stick around and make sure they don't get themselves killed.
"Steph, grab Damian and get somewhere safe. Don't wait for me. Go NOW!" As much as she'd like to stay by her friend's side, dealing with the gunmen would be just as effective in assuring their safety. She found a table and flipped it over with a loud thump, crouching behind it and hoping they weren't using armor piercing rounds. A guy tried to attack the gunman with about as much success as Kate would expect from a random dude who by the looks of his attire wasn't invited to the wedding. Who the hell was he and why was he there? Questions for another time. Another guy thought he was Captain America and threw a plate. And then a girl tried giving the bad guys a drop kick. They had resolve, she'd give them that. But strength is about fighting smarter, not harder. Judging by the magazines those guys were carrying, they had about 30 rounds before they had to reload. The bastards already wasted at least 10 of those spraying and praying. Be patient. Wait 'til they're out. Sometimes best course of action is to take none.
