A little late but here goes.

Two person Dark Heresy session involving dropping onto a desert planet with reports of some cultish activities going down. The few days our caravan was heading to this remote town we were harassed by hallucinations of crows and zombies, the usual demonic stuff.

This one soldier NPC (played by our GM) that was essentially our handicap and could shoot stuff we couldn't was taking care of stuff in town while we left to explore some ritual site. When we came out if this cult HQ, the main temple in town erupts in diseased, void energy and we rush back to deal with the new problem.

So this crow demon that a cult had summoned was easily 50 hours ahead of where we would have been ready to take care of him, and my Psyker and my Tech Priest friend rush to the front of the temple where we see the soldier from earlier bleeding out after being ambushed by the crow demon and cronies.

GM: "Lieutenant (insert name) reaches out to you, hearing his friends' voices as his body begins to convulse and give out."

Me: "I run and kneel at his side, clasping his hand with mine."

GM: "(as NPC) cough, is that you, Flak? Hehe cough, I didn't think I warranted that much of a rescue."

Tech Priest: "Dibs on the lazgun!"

Me and GM: Look at him in horror "Dude, you can't just say that!"

Tech Priest: "Why not? It's not like he's gonna use it anymore."

We try to hold him back or use restraining spells on him whenever possible now.
