Two mountings down of the third set, and the scaffolding shook. He turned quickly, the melta brought to bear, revealing a pair of ice blue eyes and a concerned face staring at him. He took a sharp breath as Bethany stepped towards him, a look of confusion on her face.
No time to explain. Verbally, at least. He pointed at the mounting, then shot it until it melted free. He held his hand vertically, then slowly tipped it horizontally. Bethany seemed to get that, drawing her weapon. Quickly, Klightus shook his head, pointing to the other set of scaffolding across the courtyard. She nodded, understanding his intentions perfectly. She turned, activated her pack, and shot across the courtyard to leave Klightus to his work.
As he worked, he could hear her weapons firing. Excellent. The third set freed, the fourth, the fifth... He was working on the last set of mountings when he heard the whine of Bethany's jump pack. Glancing back, he saw the other scaffolding toppling over... By the Emperor's grace, it stayed together as it landed on the ground. Between the two of them, the final mountings were freed from the wall. At this height, all it took was one push to make it wobble, and a little more to make it slowly tip.
As gravity began to do its job, Klightus remembered the downside to this plan -- he was on top. He looked to Bethany, fear filling his face. She, in turn, grabbed his pack straps and fired her pack. There was a moment of near weightlessness as they dropped, but her pack wasn't designed to carry two people. They landed, hard, sending them both sprawling onto the ground. But despite the scrape on his arm, they were alive. The choke point might not have been very tight, but it was still something.
As they ran back towards the line, he saw the squad of Celestians loading up into the Rhino. Klightus found himself smiling. There was the possibility of winning this now...
