Seeley Booth is a former sniper with the U.S. Army Rangers. He now works with the FBI and alongside the team led by Dr. Brennan.
At first, Booth was not happy to act as a liaison between the FBI and the Jeffersonian Institute. But he eventually developed personal and professional chemisty with Bones. They now with a top notch crime-fighting unit.
Booth is an ideal complement to Bones' speciality in science. He's intuitive and knows how to read people.
Booth: I worked really, really hard on my vows, but you know, now that we're here, look, um, hey. Do you remember the last time that we were here? Standing right around in this spot? It was right in the beginning before we really knew each other. I was trying to get away from you because you were irritating me and, uh, you chased me down, and you caught up to me and I said to you 'listen, I just have to get all my ducks in a row' and you said to me--
Brennan: I can be a duck.
Booth: Yeah. You know we had been chasing each other for a long time. Chasing each other through wars and serial killers and ghosts and snakes. And now chasing you has been the smartest thing that I have ever done in my life. And being chased by you has been my greatest joy. But now, we, uh, we don't have to chase each other anymore because we caught each other.
Hodgins: Where's your chest hair?
Booth: I'm highly evolved!
Brennan: His pubic extension is entirely within normal --
Booth: Okay! Enough!
