LeeRoy was sure he was going to make it across the room, he was fast enough in his suit to travel that distance in less than a few steps. And he was in sprint, so the concept of Khazna catching up to him was mind boggling. Mid stride it became quite evident that his plan was about to backfire horrifically, this horrifying backfire was only further cemented when a blade penetrated through his backside again and cleaved through his spine in one movement. The blade was withdrawn and LeeRoy had to act before a second slash was delivered. 

'Did he just!?' In his mind the Voidman screamed out in horror, watching LeeRoy get gored was never a pleasant sight. Especially since she witnessed it in first person and third person simultaneously, there was nothing pretty about what was happening right now. And LeeRoy knew it would only get worse if he didn't act fast. 

Without thinking about the repercussions he plunged his thumb down on the button for the C4 stuck to the wall. Halfway through the room, less distance between him and the wall was a good thing. Why? Well that's because Khazna's in the way of the shrapnel blast and powerful pressure wave, that's why. With the detonation of his explosive there was a 50/50 chance of getting shrapnel in his back, but it was better than decapitation. And since Khazna would NOT be expecting it, and since his position was compromising he was likely going to get a back filled with hot steaming metal thrown at well over penetrating speed. Oh, and the concussive force produced by the explosion, can't forget that.
