The swarm keeps their place only through fear and sheer force of will as they watch Punk crumple into a bloody pile of meat and bones, that red red coat blending into the pool spreading far too fast for anything to have survived. Somehow, the husk of what had once been Greenhorn looks even emptier then ever as he helps Nico stand and the two turn to walk away from the mess of someone both the Plant and the swarm had called brother.
Nico looks paper white, barely standing. They understand fear and survival. Now they understand guilt too.
Had they not taken Vash's friends here, perhaps he wouldn't have come at all. Perhaps they wouldn't have had to learn and understand
They move without completely realizing it, straightening and striding with purpose around the corners separating them from the others, from the one who killed their second brother and just left him in a pile on the ground--!!!
Zazie rounds the last corner at a near run, every single Worm in their swarm vibrating in a swelling sound of pure insect rage. But they stop before nearing the other two, enough logic in the Hive itself to keep the little swarm from foolishly attacking the monster walking away from them. The swarm is only vaguely keeping their form together, mass shifting and flexing as whole insects peel themselves away from the whole and resettle, only one large, poison-green eye with hair thin slit left whole and unchanging, staring after the Plant and Nico.
They say nothing as the planet itself rumbles with the Hive's anger, only turning to drop next to Punk when they go, looking for anything, anything at all, that might be a sign of life in him. They don't think the medicine syringe they now hold clenched in a mostly solid fist can heal that which isn't living but it won't stop them from wasting a vial anyway. If not now, when would they even bother?
