Blood was splattered up his hooves, though less than there could have been since most of the injuries he'd inflicted never broke skin. His body was tensed with anger and distress, the latter picked up from Brynn. Even though he knew the pheromones were hers, being an animal with heightened sensitivity to the emotional state and arousal of others made it hard to ignore them. A horse's body was even more geared for gathering such signals than a human's, so he was more affected in this form.
Skittish despite the anger, he moved uneasily away from the body and back towards Brynn. The fear and distress twisted his insides more the closer he got to her. The alarms ringing made him flatten his ears in annoyance before pricking them forward again as he got close to Brynn's huddled form, lowering his head to nudge her with his muzzle. He could hear the footsteps of the guards as they ran away but knew that soon enough someone would get brave enough to come back to find out what happened. The alarms told him that much.
