Castle, Season 2

[Beckett, unsure if she can continue the case, speaks to her father]

Jim Beckett:
Your mother always said that life never delivers anything that we can't handle. I mean, she lived by that, you know. Called it "Johanna's Immutable Law of the Universe." And for years, I thought she was wrong. Because I couldn't handle losing her. Now, I can almost hear her whisper, "I told you so."

Beckett:
[smiling] Four of Mom's favorite words.

Jim:
Look, she was a devout believer in the truth. And if she were here right now, she'd tell you the truth can never hurt you. You know, this may be your mother's way of reaching out to you, Katie. And reminding you that the truth is still your weapon to wield. Not theirs.
