Bryce had gone to his patrol that evening after healing Rhea of the poison that afflicted her. He was tired on that patrol, to be certain, but he usually has a good estimation of how much healing various injuries will wear him out and wasn't too worried. He had a bad headache, was a bit crabby and tired, but didn't really have too much trouble getting through the shift. He figured he would recover from it while he slept between that shift and his next. While on the shift he told the other men about the large badger-type creature that assaulted the tavern, and how Biske and some others fought it down.
Rhea had insisted that it was the demon blood that poisoned her, and he could only assume she contracted it through Biske when she tried to heal him. Biske had suffered wounds from the creature that attacked outside the Dagger, and it made since that it would affect him. Bryce didn't really expect to get poisoned himself from the blood. Sure, it had splattered on him, the stuff had splashed everyone that was there, but he never actually took any injuries.
He was sluggish when he woke up in the barracks, still beat, but he figured once he had breakfast he would feel renewed. Usually it's a quick rebound from exhaustion due to healing. After his morning meal of whatever slop the cook passed for food, the young aspirant attended sword drills. By the time they were leaving for patrols he was coughing and feeling even more fatigued. A couple hours later he was lagging and the cough had become chronic, his face adopting an unhealthy pallor. He was quite adament that he could finish his patrol, but it was soon obvious that this was poor judgement on the healer's part in regards to his own health. Eventually they sent him to go rest back at the barracks.
Hopefully Agnie wasn't on the patrol with him, that would have been insult to injury.
