Let it be known, I've not been trying to say Urgrugg's little tiff with Xeph would go unnoticed. Fire alarms would be going off, screaming and yelling would be alerting guards, the machine spirit would likely register damage to and unsanctioned opening of the prison cells. The dead commissar not reporting in would definitely raise some flag.
No no, I'm just saying it wouldn't have pinged on any psyker radar. I phrased it poorly, but I meant our element of surprise has been taken away; they'll be expecting psyker trouble when they come for us. The ship would have been alerted to our presence as soon as Xeph had a fist fight with a solid metal door. We're in a giant, metal tunnel. That shit echoes, man.
