Dr. Temperance 'Bones' Brennan: I'm... quite strong.
Special Agent Seeley Booth: Yeah, well, you've always been strong.
Dr. Temperance 'Bones' Brennan: You know the difference between stength and imperviousness, right?
Special Agent Seeley Booth: Well, not if you're going to get all scientific on me.
Dr. Temperance 'Bones' Brennan: Well, a substance that is impervious to damage doesn't need to be strong.
Special Agent Seeley Booth: Hmm.
Dr. Temperance 'Bones' Brennan: When you and I met. I was an impervious substance. Now I'm a strong substance.
Special Agent Seeley Booth: I think I know what you mean.
Dr. Temperance 'Bones' Brennan: A time could come when you aren't angry any more and I'm strong enough to risk losing the last of my imperviosness. Maybe then we could try to be together.
