Guilian was momentarily distracted by a somewhat familiar face on the battlefield, one who was looking towards the woman he was fighting. Cass Vaisey. Cass Vaisey who was looking directly at him. Oh bloody buggering hells, he didn't need that right now. The only thing worse would have been his brother staring him down on the battlefield, and they were on the same side.
Somehow, he didn't think that would stop his brother from hexing him if he discovered he was here.
In the moment he was distracted by Cass, he was struck by a hex. Nasty boils broke out under the robes on his chest and he cried out in anger, and annoyance.
A hurling hex flew from his wand, aimed directly at the woman, as he took a few steps back in pain, clutching his chest as the boils began to pop and ooze. So what if you didn't use hurling hexes on people. He was beyond caring.
