As the vampire bats pitched themselves below the canopy to swoop on them, Jack smoothly brought Thunderdell's barrel in line with the first of the pair targeting her. True to it's name, when she pulled its trigger Thunderdell let out a thunderous boom. The cannon shell ripped through the relatively small Grimm, leaving little more than pink mist in its wake. That close up, bass report of the heavy munitions dazed the other bat. Unable to tell where it was going, it collided face-first into the ground barely two steps from Jack. The impact wasn't enough to mortally wound it though. Lifting itself shakily from the ground, it shook its head and started to regain its bearings... just in time to see Jack swing her weapon down like an executioner.
With her two dispatched, Jack commented to her new partner. "Ugh. How much you wanna bet there are more?" Expecting he'd already killed it, she turned to see how he was fairing against his own bat.
