The fact that your nickname across Rainbow's files and analysts was 'Dexter Morgan', wasn't exactly a coincidence.
Because simply put, you were a serial killer. And a wealthy one, too. Being a rather big business tycoon, as well as a Wall Street investor earned you a rather steady cash flow. But the dinners, the lavish hotels, the leather seats of your Rolls Royce just left you more apathetic than anything. Apathy then turned to resentment, for those steaming assholes you had to deal with every day. So you started inviting them over for private meetings, excursions, fake dates. Methods varied based on your mood: silenced pistols, knives, or just drowning them in the indoor pool (couldn't use the outdoor, it'd make too much noise). Every time you did it, it became easier, some form of sick catharsis. Until one kill too many, specifically one of Rainbow's lead contractors led Ash into an investigation.
Which landed her at your door. You played it calmly, invited her in, and left to get you both drinks. But as you came back, Ash had a file on her coffee table. And an FN 5-7 in her hand.
