Adrian was running madly through the city. As soon as he confirmed that Wraith No. 4 was dead, he felt multiple pairs of eyes falling on him. It was to he point where they even stopped their fights to stare at him.
It wasn't just their gazes he felt thought. He could feel the killing intent radiating from among a few of them. Of course, it didn't take a genius for him to know where this killing intent came from.
It came from the rest of the Wraiths. If looks could kill, Adrian was sure that he would have been dead multiple times over. That was why he quickly bolted out of there.
Since his disguise was undone, he didn't want to give them the chance to get a good look at his face. Since they were relatively far away, he felt that they would have a hard time getting a good look at his face.
