"Heh. Oh how the mighty have fallen," Levi taunted, a smug grin as he began getting off the ground and dusting himself off while the merc was distracted by David the Big Goddamn Hero's entrance into their little skirmish, bloodied weapon in hand. And as the merc was still distracted, Levi began unveiling a few of his toys from his bag now that his previous gambit had worked its magic. Admittedly it was pretty risky, but it all worked out in the end, right? And now there they were, 2 vs 3. 

Levi was fucking [i]juggling[/i] grenades in his hands. Tossing one grenade from left to right, and the other from right to left at the same time. It wasn't circus-level juggling, but the dexterity and motor control needed to do so in the first place! No wonder the kid was so great with lockpicks. "So dickweed," he started nonchalantly, further humiliating the interrogator, "You wanna know a secret?"

Levi mimed pulling the pins from his grenades and threw both of them at the man, all inactive. He sent another wave at the man before charging in, actually pulling the pin from the one he had in his hand. The other 'nades were to pin the man down psychologically while Levi could go in for the kill. "One: I'm not actually Weaver's son," Levi said, thrusting the pin at the interrogator's eye, "Two: Mines beep before they explode." If the pin got in the eye, all well and good. Then he'd stick the 'nade in the man's mouth as he screamed, or maybe down his shirt if he didn't, before dashing off to victory. If the guy managed to deflect Levi, he could still throw the grenade at least, and there'd be no dodging that, it was already cooked enough.
