Why then?
Why had the monster blown itself up at that moment? She remembered the way it had started to shift, new limbs bursting from its body as it watched her. If Prax was right, that was the moment the constraint systems that Mao’s scientists had installed failed. And they’d set the bomb up to detonate if the creature was getting out of their control. But that just pushed the question one level back. Why had their control over the creature’s physiology failed at that precise moment? Prax said that regenerative processes were a good place for constraint systems to fail. And her platoon had riddled the creature with gunfire as it had charged their lines. It hadn’t seemed to hurt it at the time, but each wound represented a sudden burst of activity inside the creature’s cells, or whatever it had in place of cells, as the monster healed. Each was a chance for the new growth to slip the leash.
Maybe that was the answer. Don’t try to kill the monster. Just damage it enough that the program starts to break down and the self-destruct kicks in. She wouldn’t even have to survive, just last long enough to harm the monster beyond its ability to safely repair itself. All she needed was enough time to really hurt it.
She put down the armor plate she was working on and picked up the helmet. The suit’s memory still had the gun camera footage of the fight on it. She hadn’t watched it again after Avasarala’s presentation to the crew of the Roci. She hadn’t been able to.
She pushed herself to her feet and hit the comm panel on the wall. “Hey, Naomi? You in ops?”
“Yep,” Naomi said after a few seconds. “You need something, Sergeant?”
“Do you think you can tell the Roci to talk to my helmet? I’ve got the radio on, but it won’t talk to civilian stuff. This is one of our boats, so I figure the Roci has the keys and codes.”
There was a long pause, so Bobbie put the helmet on a worktable next to the closest wall monitor and waited.
“I’m seeing a radio node that the Roci is calling ‘MCR MR Goliath III 24397A15.’”
“That’s me,” Bobbie said. “Can you send control of that node down to the panel in the machine shop?”
“Done,” Naomi said after a second.
“Thanks,” Bobbie said, and killed the comm. It took her a moment to re-familiarize herself with the Martian military video software, and to convince the system to use out-of-date data-unpacking algorithms. After a few false starts, the raw gun camera footage from her fight on Ganymede was playing on the screen. She set it to endless loop and sat back down on the deck with her suit.
She finished bolting the back armor on and began attaching the torso’s power supply and main hydraulic system during the first play-through. She tried not to feel anything about the images on screen, nor to attach any significance to them or think of them as a puzzle to be solved. She just concentrated on her work on the suit with her mind and let her subconscious chew on the data from the screen.
The distraction caused her to redo things occasionally as she worked, but that was fine. She wasn’t on a deadline. She finished attaching the power supply and main motors. Green lights lit up on the hand terminal she had plugged into the suit’s brain. On the wall screen by her helmet, a UN soldier was hurled across the surface of Ganymede at her. A confusion of images as she dodged away. When the image steadied, both the UN Marine and her friend Tev Hillman were gone.
Bobbie picked up an arm assembly and began reattaching it to the torso. The monster had picked up a soldier in a suit of armor comparable to her own and then thrown him with enough force to kill instantly. There was no defense against that kind of strength except not to get hit. She concentrated on putting the arm back together.
When she looked up at the screen again, the feed had restarted. The monster was running across the ice, chasing the UN soldiers. It killed one of them. The Bobbie on the video began firing, followed by her entire platoon opening up.
