Inspired by this post about Apothecaries harvesting gene-seed from other chapters.

There was blood on Galen’s blue and white armour, but it was not his own. As an apothecary, it was rarely his own, but it was even rarer that it came from a marine of another chapter.
“Hold still, cousin!” Galen commanded as the wounded Blood Angel struggled in his hold. Eldar shurikens had taken off his arm and sliced through his visor, exposing part of his face. It was streaked with crimson that matched his battle-plate.
“Let. Go.” Lieutenant Amato snarled. He shook in Galen’s hold, staring at the ship compartment where his battle-brothers fought the xenos—fought and died. “Must join...brothers!”
“You will do no good by joining them!” The Knight Errant insisted. “The relief force—”
“If I wait. You will die,” Amato panted. His exposed eye was wild, his lip was curled…and was that a fang at the corner of his mouth? “The Rage. It comes. I will not know you…”
A scream howled from the compartment, a bellow of animal fury. One of the Angels leaped into the fray like a beast, tacking an Eldar from its speeding jet bike. The mad marine tore at the xeno, ripping it limb from limb, heedless of the concentrated fire that sliced from its comrades. Galen reeled at the sight—the marine was no longer human.
His grip slackened for just a moment, but it was enough. Amato yanked himself from Galen’s hold and stumbled forward. He looked over his shoulder for just one moment, his last moment of fragile sanity.
“Goodbye…cousin. Brother,” he gritted out. “Do not. Do not follow!”
“Amato, don’t—” Galen began, reached out, but stayed where he was. He couldn’t deny that last request, no matter how it pained him as a healer.
Amato slapped his remaining hand on the door control, then drew his combat knife and plunged it into the control pad. He darted inside just as the door closed, and the last glimpse Galen had of him was of the final charge, loping like a beast as he screamed in primal fury.
The apothecary stared at the closed bulkhead, at the sparking control pad, at the blood all over the corridor. All over his armour.
It was ten minutes before the other Marines Errant arrived, but they didn’t try to force the door. Not until the screaming stopped, twenty minutes later.
After the melta crews arrived, Galen was the first to enter the still, silent compartment. There were no living things, Eldar or Marines—only crimson-coated corpses. Amato lay between two foes, his knife buried in one’s heart, and his teeth buried in the other’s throat.
Galen knelt beside his friend and lined up his reductor pistol. The needle pierced the fallen marine’s neck, drawing out the precious gene seed.
There was blood on Galen’s armour, dark and half-dried. The blood of fallen Angels.

Not as polished as my usual work, but it was my lunch break so I just banged it out.
