Booth and Brennan in “The Memories in the Shallow Grave”

Booth

I just...I want our kid to know that I'm not my dad. I just want him to know that I was a good dad who gave him a real home. Our home.

Brennan

Why didn't you just say that?

Booth

Just didn't think you'd understand.

Brennan

[shakes head incredulously] I don't. I know you're not your father.
