Not sure how many they mentioned, but they only pieced together their Sylar theory after finding multiple weird X-Files if you will and that was even before the incident with the little girl. They had already put their profile together before that murder.Is Sylar his real name? Just wondering because the FBI agents called him Sylar, so wondering how they know his name? Just trying to remember when Mohinder listened to the tape, did it specifically mention his name and if so, again how the heck do the FBI agents know his name? Supposedly the main trait of his crimes are that there is no trace.That leads me to another thought, could one of the two women FBI agents is working for HRG, Sylar or Mira's company? Sure seemed like the lead agent wanted to get nuclear guy out of there quickly. Even if Matt is suspended, didn't he read minds in front of her as well as the blonde one? If so, what would be the harm, couldn't it help?
