Nicholas was angry when he arrived back home from visiting Leonardo at the hospital. He was angry because they were discussing the problem she had with one of her superiors at work. The conversation went on for about fifteen minutes, and during that period, he just watched as they talked, he couldn't say anything on the topic since he knew nothing about it. How could she make him feel so useless in the presence of her best friend and his cousin.
It was as if she deliberately did not want him to know about the man. This is the same Percy who wanted to sue her for assault and he remembered quite well that he asked her to tell him the problem she was having with the bastard and she refused. She told him that she didn't want to discuss him. Her exact words were...
'his name always leaves me in a bad mood and a bitter aftertaste in my mouth'
