Currently, we have about 4 options at least to make this work: 

1. One of us control him mainly for about say 2-3 posts then switch over for another 2-3 posts before killing him.  
2. We talk it out in the OoC as we're writing it, discussing options or what should happen in each other's posts. 
3. We do a collab with [@Dervish]'s blessing. :p
4. Or, have a third party like another player (not necessarily those involved in the scene) or GM take over Kaza's posts for the time being.  

Another distant one is that Haze or Vellios goes to help Vallis who's currently out numbered and having a hard time, mainly because the thugs aren't taking chances and chucking grenades at her repeatedly to limit her botic options. If too many grenades, by the GM's choice, are tossed depending on the building's integrity could result in either one or two results: 

1. Tonnis becomes a demolition expert and [i][u]tries[/u][/i] to bring the whole building down on top of the mercs. Key word highlighted there because it will most likely be stopped. 
2. The integrity of the building is much weaker and shoddier than any of them realize causing it to start to crumble the roof a bit down on top of them though not completely collapse.

If not, I'll figure something else out or merely have the others do that.

If you guys really wanted to do a collab, I'm alright with that. I mainly just wanted to steer people away from making it the go-to posting idea. 

As for the grenades make buildings go collapse thing, grenades simply wouldn't cut it, even if you had a bunch of them. Pretty much the only structure getting brought down by a grenade is an enclosed tin shack that can't contain the force of an explosion. You'd need demolition charges and a considerable amount of time and planning to take down something like the warehouse; it's a very solid building. 

Tonnis, or any of the other Twin Star jackasses, also probably would be hesitant to try and destroy their own infrastructure. Even if you succeeded in doing that to kill a handful of intruders who seem to have the upper hand, you'd still have to deal with the whole fact you collapsed a building and everything important you were storing inside of it.

I also wanted to point this out from your last post,

[i] The Turian was pushing up with his foot and rushed at Kaza’s upheld gun pointed at him. A second later, Batarian pulled the trigger.

When the barrel starting to flash as the bullet exited the chamber, Vellios brought up his free hand. It clasped about the wrist and jerked the muzzle to the right.[/i]

Unless Vellios has Neo-like reaction time and can perceive things in slow motion, this scenario is impossible. Trigger gets pulled, fraction of light speed projectile immediately leaves the barrel. Reaching up to push the barrel away after the trigger was pulled is simply impossible. It would make more sense that either Kaza's shot missed (which isn't unreasonable; if you're trying to react to somebody suddenly bullrush you from blank range, you may shoot before you aim), or Vellios got to him before he could shoot.

The scene doesn't really have to play out any different, I just wanted to point out that our dear turian isn't going to be able to defy physics, no matter how dramatic it is. :P
