You What?

"You want me to spy on my best friend? Do you think I am some specialized agent who can do that?" Isabella asked incredulously staring at Ian as if he had just asserted that he was The Pope. 

Ian shook his head and sighed," Spy is such a harsh term, Bella. And it implies passing on information. You don't need to do that. Nora is already under surveillance from some top class security experts. However, Demetri does not want her to know, for the time being. So, the best way is for someone to always be around her on the off chance that she decide to ditch the security or get suspicious. She's got sharp instincts."

"She had to have those. Or else she would not survive this long. So, you want me to act a as a safety blanket to help maintain the ruse that all is well?"

"Somewhat like that. If Demetri or one of us stick to Nora all the while, she will get suspicious. But with you, she won't be that wary, I think."
