Bones, Season 8

Singer:
You think I killed him?

Booth:
The photo you took of him is the centerpiece of the show.

Singer:
But I didn't know that! People change between the age of seven and twenty four! [Brennan looks at Booth] You know, I have seen enough death, thanks! I have no interest in killing anybody myself.

Booth:
Have you gotten any help, Miss Singer? [Singer looks at Booth in surprise] I'm a veteran. I can recognize post traumatic stress disorder.

Singer:
Yes. I got help. I had trouble sleeping, I had dreams, I got depressed. But I have my work and I never killed anybody. [to Booth] Can you say the same thing?

Booth:
No, I cannot.
