Herold had thought he would have gotten used to the chaotic warp magic of the Psyker, but feeling the tingle of his skin and the odd feeling in his gut, he knew he had been mistaken. The explosion of the gun and the Ork was well placed, but it had announced their location a bit too much for his liking. Still, unless the Sororitas ordered him to unload his combat shotgun into the Psyker, then they were stuck with her still. He could tell that the others had to visibly hold themselves back from what he was just considering. 

"Agreed," Herold said to both Aviza and the Death Korp trooper. "Let's get moving." He made sure for the umpteenth time that his weapon was locked and loaded, and he started to head out of the room they were in with the others. He kept his shield on his back to guard against flanking shots, and his shotgun in his hands and at the ready. He had an inkling feeling that the explosion was about to bite them in the ass somehow, but Emperor's mercy, they'd see soon enough.
