The real chief

If it were Sen or Jasper, Cassie could have understood what they meant by those words. If she thinks of it normally, he warned her to keep her energy low or it would not take long for others to find out her real identity through her aura and smell but Aegir didn't know she was a vampire so why? 

Was he able to guess her identity and that's why he warned her to stay cautious? Even if that is true, won't he come to hate her after knowing she deceived them and more for her real origin. 

She was left stunned staring blankly at only one place lost in her deep reverie. Then after a few seconds she started to blink and exhaled. 

Whatever, it's not like I can hide it forever but what worried me is the current chief of the vampires. It's been months yet he didn't make any move. What is he thinking? By now he must have known that my strength and powers are back to usual still he didn't make any move, just what the hell he is planning to do?
