Capítulo 98: I killed them all

He was a direct subordinate of Lord Jaffrey. He had another name, a title under his master, EXECUTIONER.

"What is that supposed to mean? And why are your clothes so dirty??" Ian asked in a furious tone

He was already quite annoyed with the pressure of mission which was putting his life on the line.

He could not bear to have bullshit from Harry. Also, Harry smelled really foul at the moment which made it worse for Ian's already foul temper.

"Wait, is that? Is that blood that I am smelling from you??" Ian asked in surprise

Suddenly, Ian recalled the title of the rogue like man in front of him. Even though that guy called him Sir and generally gave respect to Ian, he was a mad killer, famed for his cruelty against nobles. 

Ian had his mood changed in an instant. He had gone from furious to nervous very quickly. Ian looked at Harry warily. His post nut clarity had helped him to analyze the situation.
