"That's it, I've had enough of you. I was willing to look past the whole 'attempted betrayal' thing but you really are just an arrogant little prick, aren't you?" He heads for the door... and turns on his heels, slamming his gloved fist into Three Star. To emphasize the point, he activates the shock matrix.
We can resolve this through RP or you can roll initiative and count that as a surprise attack. Up to you .

[RHat]

Jimmy was glad he'd had his wires on already - he drew his Thunderbolt and slammed 6 gel rounds into Marduk's chest.  "I am a patient man, but I am NOT going to put up with this brand of bullshit from any of you.  I've got two clips loaded in here; either of you want to find out what's in the other one today?  You really want to gamble on the odds that I'm loading two kinds off less lethals?"  He stared the two of them down.  "If you two can't work together without attacking each other, walk.  Steelfish and I can figure out something about finding replacements.  I don't give two shits what you two think of each other, but so long as we're on the same team I will not tolerate violence against anyone else in this crew."

[Retrokinesis]

Marduk snarled and, with a flick of his wrist, his Thunderbolt launched into his hand. He gritted through the pain of the LTL rounds. "I was willing to be reasonable. Now? I'm just going to fucking shoot you". He raises the pistol and Jimmy and pulls the trigger.
So both Three Star and Marduk are technically injured at this point but we haven't rolled any attacks yet. How do you want to handle damage?

[Retrokinesis]

Anyone who was paying very careful attention noticed a faint smell of ozone when Marduk punched Three Star. When Shark shot him, it become unmistakeable. Now you can see why. An enormous crash of thunder sounds and a swirling vortex of freezing air appears in the center of the group. Vaguely humanoid, its enormous form shudders as tendrils of crackling cloud reach for Marduk and Shark and begin to choke them.
The guardian spirit is now manifested and attempting to Engulf anyone with obvious weapons. You can attack it if you wish but it will escalate to lethal force. Anyone not involved in the fight should probably indicate that very clearly. We can play this out as an actual combat encounter if you guys want but, spoilers, it's going to absolutely demolish everyone if we do.

[RHat]

"Oh, *cough* sure, *cough* this is *cough* what I get *cough* for trying to *cough* stop the *cough* fight."

[Retrokinesis]

"That's ENOUGH!" A voice rings out from the now-open door to the room. Steelfish stands there, glowing with obvious defensive spells. "Release them". The spirit dematerializes, no doubt lurking on the astral reflection of the room. It's tendrils gone, Marduk and Shark can breathe again. Marduk collapses to the floor from the combination of Jimmy's shots and the choking haze. Jimmy is still conscious but his vision is fuzzy and every breath is painful.

"You have 10 seconds to help me grok this situation before I call the spirit back and have it tan your damn hides. Go".
Marduk's health track is full of stun damage and Jimmy's is half full.

[RHat]

Jimmy coughs a bit before answering.  "Asshole 1 decided to haul of and slug Asshole 2; I decided to try to stop the fight, at which point Asshole 1 decided to fire off some lethal rounds."  He thought for a second.  "By the way, you might want to have you spirit consider people trying to keep the peace to be, you know, allies..."  He took a moment to gather his senses.  "Look, we're obviously going to have to figure out how this is going to work here, because this drek is in no way acceptable."

[umraefein]

"From where I'm standing, all three of you are assholes. You all either attacked each other, or pulled weapons on each other... in a room you knew was warded. Thank you for intervening omae." Ignazio shook his head, wondering what was wrong with this group...

[odd]

Tink seems to notice what's going on for the first time"Hey..what did I miss?"  He zones out for a second and comes back.  "Ah, you guys are fighting again.  Nice spirit bee-tee-dubs Mr. Steelfish, very creepy looking.  I think we are going to have our work cut out for us without killing each other though."

[Retrokinesis]

Steelfish nods to Draco and Tink. "Appreciated. Now what are y'all gonna do about this? Am I going to have to separate you children or can you act like adults? Because if y'all start pullin' this drek on a job you'll be lucky if you live to argue about it".
Draco, considering you're dual natured, you could make an Assensing check to get an idea of how powerful Steelfish and/or his spirit are if you wanted.

When Marduk decided to get up for the door Three Star switched on his wires, considering stabbing him in the back now rather than later, then deal with the bar's defences afterwards. While wondering if Marduk was thinking the same, the Elf confirmed it by throwing his fist around at Three Star's face. Thinking he must at least concede to the psychopath's agility being better than him he made sure to dodge out of the way as best he could, rising out of his seat to his left as quickly as possible. The strike grazed his cyberarm, and he felt the dull sting of what he assumed must have been a shock gloves, as the current mostly diffused through his right arm's armour.

Before Three Star could do anything else he saw Shark pull his firearm, and his blood boiled upon seeing the thunderbolt. The rounds struck Marduk to his suprise and the blonde man paused long enough to not jump to a violent act before the spirit descended.

Yeah he's fine.

"Let's face it. That was inevitable with our tempers, Steelfish. It was best it happened now in a controlled enviroment rather than over in London."

[Retrokinesis]

Marduk is still lying on the floor. He mutters something about "glowey fireflies" before snoring, apparently now asleep.

Steelfish sighs, "Yeah, I suppose you're right. What about the rest of y'all?" He raises his hands, "I'd throw some healing spells around since you're already on a job, but nobody took any serious damage".

[RHat]

"But it can't happen again.  Ever.  So I'm going to make this real simple for the lot of you: if you have a problem with anyone on this team, you bring it to me.  Understood?"

[Chrona]

Three Star pulled out his commlink, the nanites in his blood showing only a minimal effect from the shock glove. "I'll be fine, you can skip to Shark."

[odd]

"I'm not great at healing but I will try if noone else wants to."
