The explosion was successful at preventing a decapitation, but being thrown through the air while the entirety of your body is numb is an unpleasant situation. His eyes caught something in his hand mid flight, the detonator was still there. Swell. All of the force from the explosion had sent his body into some sort of strange flailing spiral of motion with the man who was trying to kill him right behind him. Well, from the neck down he can't feel anything anymore, questioning how he pushed the button himself. Probably just the muscles tensing up, or maybe divine intervention. Sometimes these things are best left to suspension of disbelief. 

'You're fucked aren't you?'

"Yep." His voice was gasping and unnatural, his lungs had been cut, crushed, and now completely nerve dead. But the words escaped him, and he looked to the ground swiftly coming up below him. His hands limply flopping behind him as he faceplanted into the metal flooring. And then, inconceivably, the worst possible thing happened. Literally the worst possible thing. As Khazna and LeeRoy landed the detonator landed button down, button down on the ground. His hand had fallen thumb first, the detonator was in that hand, and the button touched the floor. As khazna rose to his feet LeeRoy swore to himself.

"This just got a whole lot fu-" He was going to say 'a whole lot fucking worse.' But the C4 in his right forearm detonated while still inside of his suit's storage compartment. Literally impossible for LeeRoy to dodge in any regular way it would have even more dangerous repercussions for those around him than the previous bomb. This time it was in a container of plating and metal, with LeeRoy's innards to add to the mix. As well, the 16 other explosive charges were detonated by the C4 block, and their small explosive nature was still more than enough to reap havoc with LeeRoy's body. The Voidman and LeeRoy himself groaned internally as a brutal explosion tore his body apart, bombarding everything in the hallway with scalding hot chunks of LeeRoy and his suit.
