The sheer amount of firepower that Hayden unleashed in the room after the grenade went off, the spray and pray emptying anyone left standing in the room, turning the entire place into claret and dust, 

"Cover our six, Beth!" Sean yelled out, moving in, the FAL pivoted at point-shooting position, bodies all over the place. Walking over them, Sean's ears were ringing, the FAL's barrel hot yet still loaded with a full mag for this breach. Nobody would have survived that grenade, yet Melani was still there, limping on the floor, blood pouring and sheer violence fuelling her. 

As Melani raised her hand, Sean was faster, more driven as he threw his leg straight at her lower arm, the rebar that followed hurting as it clattered into his leg, but enough to give Sean time to point the FAL directly at her top half and pull the trigger, spraying a handful of rounds at point blank, and immediately doing the deed. It wasn't like some Hollywood movie, where he got to say something, and so did she. It was just a desperate situation ending as frantically as it would, Sean looking at the growing pale on Melani's face, her violent, fucked up, psychosis put to an end.

One of probably dozens in this suburb alone, the Ulsterman thought to himself. And they were probably joining her.

"Jesus. Even in fucking death, you're a cunt." Sean spat, looking around the room, shaking his head. With a pull of his knife, Sean looked at the dead corpse of the woman, just thinking only that it wasn't a fitting way. Dying quickly, rather than slow- he was nobody to judge but even so, knowing the shit that went on in her little kingdom made even his stomach turn. So in some ways, it was poetic what was coming next. He was disgusted by what he was going to do, but it had to be done, given the situation. They'd struggle to get back to the turf they were contracted for, but if they could at least get there and leave what was proof of Melani with one of Edgar's grunts, it would be enough. 

With a slight cut, Sean pulled her hand up that was carrying the shiv-like machete and with a wack of his own machete slammed through, taking another hack at it and eventually, breaking the bone to bits, clattering the wrist out and pulling the hand out. A macabre war trophy, and one he threw into the pocket of his backpack, shiv in cut offhand. He looked to Hayden and Yekatarina, knowing he looked as fucked up as could be- sinking to the low level here no doubt, but aware that it was likely their only route to proving the target was down so Edgar's goons could at least buy the story.

"I don't think we can PID this the usual way, you know what I mean?" Sean commented, shrugging his shoulders indifferently, as Beth kept watch on the door, the fucked up situation and the now growing smell of dirt, bodies and blood making this place no better to be in.

Sean looked to Hayden as he stood up, taking a deep breath, his leg hurting from where he'd been swung at, the bar not making any damage but leaving a nasty bruise, masked still by adrenaline. He looked around, noticing the scene they were in, and in fact, not too distant from the part of the facility where she had her throne. And her cages, no less.
"Shit. We need to go, that safe is too nice, but we can't stay. Beth, we all good?"
"No more yet, but clock's ticking."
