GHOST reminded A of KING, and she couldn't help but become one of his biggest fans. So when news circulated to A's employer that an affiliate of GHOST was looking for someone trustworthy to help him look into something in the underworld, A was more than willing to take on the job. Her employer was stunned by her willingness, but he didn't ask too many questions and just allowed her to do it since she was one of the best at espionage in his company.
That had been two weeks ago, and since then, A has been going from place to place trying to find out anything that she could about Fiona and Gunter. News of Gunter's betrayal of the government and Fiona's disappearance was already rampant in the underworld, so A didn't have to be secretive or too stealthy while asking questions about them. No one would raise a brow if one more person was asking about the superhumans that disappeared a while ago.
