@Nykoria Tallis and @Darmus Onn were beset upon by Sirius and his reinforced checkpoint. The Sith's grin widened in response to Kori's initial words confirming both her presence and her sense of determination. This was good. Unbeknownst to Sirius however was the Jedi's plan to drop the hall on him as oppose to actually try and fight. He waited in place as Kori announced her "plan" in a stage whisper to the Ranger hiding in cover, gathering the Dark Side to himself, and then raised an eyebrow a moment later as no assault came. Boring! Well, if the Jedi didn't feel like playing the game properly then Sirius would just have to volunteer someone else. The Ranger would do.
Sirius' left arm rose up to grasp the Ranger's weapon, and weapon arm, in an iron telekinetic grip in order to drag it and the man himself bodily into the hallway several seconds after Kori had begun burning through the ceiling. Unless mitigated in some way, this would both prevent Darmus from firing his weapon anywhere but into a wall and also open him up to a full volley from the destroyer droid, which would in fact begin to fire should the Ranger make it at least partly into the hallway. If the Jedi was anything like Sirius expected, the Ranger being put into quite mortal danger would draw her from whatever it was she was up to. If Kori didn't render aid to her companion he would likely be taken out long before she had even gone through the duracrete ceiling, after which Sirius could deal with the Jedi unhindered. Sirius also began to walk forward toward the ranger, lightsaber up in a steady guard.
Of course she could always continue on with her lengthy plan, hoping the Sith wouldn't catch on, and leave the Ranger to be cut down mercilessly by blaster fire. She could take the chance of using Darmus as a pawn, a distraction to be discarded, and that his horrible death would give her the several minutes she'd need to collapse the hallway from above. But that wouldn't be very Jedi like, now would it? But if Kori did maintain her course and intend to drop the ceiling, her vanished presence and the sound of cracking duracrete would alert Sirius that something was amiss. He would then aggressively and at speed leave the hallway, through or around Darmus if still necessary. He would move forward in a guarded rush under such circumstances into the safety of the adjoining hallway, leaving the droid and the soldier to be crushed soon afterwards by the weight of falling stone.
CORUSCANT
The moment Kori felt the Force coalescing around Darmus's arm, she knew that her long-term plan was foiled. Sirius must've heard her cutting through the ceiling and acted first. As usual, the Sith exploited a person who couldn't resist the Force. And it was Knight Nykoria Tallis who had coerced that man into helping her. She had used him already, and would have done so again. But sacrificing him for a potential long shot of getting the drop on the Sith? No kriffin' way! She might have been reckless and looking for a fight, but her priorities in a fight were straight.
Stealth and subtlety were out the window. So was the need to cut the passage to the room above. All Kori would require was a chunk of duracrete large and thick enough. The lack of need to conceal her actions from Sirius meant that the Zeltron could get it done much sooner. Yet with the way things were going, she wouldn't get to that just yet. Maybe later, once the Ranger was out of the immediate danger. For the time being, the chunk of the ceiling remained dangling above. The duracrete was holding; but the crumbs falling to the ground indicated that it could get loose if yanked hard enough. Though physical force wouldn't suffice just yet.
"Hold on!" the Zeltron shouted to the Ranger, whose name she hadn't even asked in all the commotion. With her blade extinguished, Kori jumped towards him. No longer under the dangling duracrete, but still behind the corner from Sirius and his cronies, Nykoria's arms would wrap around the unknown Ranger's chest, as she'd try to pull him away from the corner; her goal to get the ranger and his weapon hand behind cover again. Kori's physical strength had to suffice; but in the worst case, she was prepared to use a telekinetic grip of her own to help her finish the job.
