Dedicated. To his job, to his country, and sometimes to his family, Thomas Mason is the director of the NYC branch of the FBI. Admittedly, he's stepped on a few people to get where he is, more than a few. People who used to be his friends are now his enemies, people who might not have had an opinion are generally swayed to the negative after getting a close look at this man's life. Why he get to where he is can only be attributed to one thing, results.


As a director in the FBI, I have to wear a lot of hats. Sometimes I'm a nice guy, mostly I'm an asshole. But I'm an asshole that gets the job done. I've been in the FBI for almost as long as I've been a working adult. I know the system, I know how to get where I need to be. I know whose ass to kiss and whose to kick. I've been on the receiving end of an H.R. slap on the wrist more than once, all I have to say about it is… if you can't take the heat, take your shoes and socks off and get back in the kitchen.



  • "Step off the soapbox for a second there, sweet tits, this call is important." — Mason's take: Really this should have been her cue to assume the position and wait for me to get off the phone. Not that I would ever cheat on my wife, but really, Powers should get it right.


  • He's got a wife and two kids (there's a .5 but unlike his wife and kids, he doesn't see the dog as part of the family)
  • His wife doesn't work (whether it's because she wants to stay at home or because he doesn't let her is up in the air)
  • He got drunk and photocopied his ass 1,000 times during a Christmas party back when he was a rookie. Someone wallpapered his director's office with all the black and whites and Mason will never live it down.
