Six-man party, reduced to four man due to warp shenanigans by one of the psykers. Then, the other psyker rolled Daemonhost on the Perils table just because she wanted to sense if any enemy was nearby. :P
Also, I was thinking: Maybe Nigel saves Arlia from her father before the two of them join up with Isaac and Hayley, which could lead to him defecting from Crey :T
That's an awesome idea! That way, Isaac and Hayley would be left guessing why the two became such close lovey dovey when they meet them again, then Arlia could engage Hayley in a cat fight after the latter dissed her British crush/boyfriend. Catfight on wings. :P
