Xileas found that her efforts to appear dark and menacing were deeply disturbed by the bickering court. She turned towards the 'drunk' and the 'uptight whore', and, in a suppressed hiss, addressed both.
"Why do you speak to mon'keigh wretches so freely? And why do you bicker so? Don't fight with words to prove superiority, fight with potentially lethal weapons, or close your holes."

Her Shardcarbine aimed on Xileas. "As much as we... Like each other, last time I checked we require of each other due to the situation we are. Or have you already forgotten about our downfall?!"

"How could I, oh incompetent fool, servant of an incompetent fool! Shoot me now, and end it, if you dare, I don't care anymore!"
Not used to walking, really, the Scourge stepped closer to the Trueborn on modified feet, not even suitable for land travel. To herself, it was a graceful, gliding gait, but anyone else would percieve it as more of a stumble, the insecure movement of a spider put on stilts.
She stopped a metre or so short of the other Eldar, her face unchanged as the unarmed winged one lowered herself slightly by bending her knees unnaturally. "If we need each other, you can't kill me, little landbound sweetheart."

Kormaily -

All he could do was grin. Getting under the Trueblood's skin was easy. What he didn't expect was the scourge to speak up about it. In Eldar. "Means to an end. I'm sure everyone here would kill everyone around them if they didn't need them for something. But I will leave it at that until our purpose has been given to us."

Arymea slapped the face of the Scourge with her left hand as strong as possible. "But I can do this!"

The force of the blow - Arymea being stronger than the Scourge - sent Xileas stumbling backwards a bit, though she was thankful for the brief sting of pain. One starved as she was didn't even discriminate who suffered as long as there was pain to feast upon.
As she recovered - still quite quick, even for an Eldar - she shook herself, her pink mane becoming even more messed up. "You can", she addressed Arymea with a smile, "but... I'll get back to you. You're just a bug, like all you other landcrawlers."

The Stormtrooper, not particularly understanding the words but getting the gist of the argument between his sworn enemies, smiles internally at the bickering

Replace them with various members of the Mechanicus, the Ecclesiarchy, and the Inquisition, and I have seen this almost exact situation a million times before, except they tend to not throw knives at the Stormtroopers keeping a watch over the whole clusterfuck of a meeting.

Kormaily -

In Gothic, "If you aren't going to drink it, then give it back. I thought maybe the familiar label would have reassured you, or even the fact that I've been drinking it would prove that it's not poison. As I said you are more valuable alive than dead. Well except maybe to our slyyth friend over there." He chuckled at the last comment and then held out his hand for the bottle to be returned.

He grabbed the bottle aswell as the slaves hand and whispered to Tyr, "Even a drunk could see you pocketing that knife. Keep it, it is no concern of mine." He smiled because the hushed conversation would have been easily ignored by the active bickering between the Trueborn and the Scourge. If the human killed any of them it would be a larger cut for himself in the end.

"And yet you will be the one at the end of the night crawling before me." Arymea replied with a smirk.

"...as I take a bite off your carcass", Xileas grumbled, falling into a more comfortable crouch and looking to the Archon.
