Castle, Season 5

Leo:
[To Beckett] Nervous?

Beckett:
No. I'm, uh, I'm just trying to send a message. They can hear static when I press the button, so I thought I'd send an SOS, but...

Leo:
It's okay to be worried.

Beckett:
[About Castle] He's gonna be fine. He's, um, he's smart and he's resourceful, so...

Leo:
Larger than life, from another world.

Beckett:
How did you...

Leo:
Please, we're in a basement. Sound carries, I heard.

Beckett:
That was a personal conversation.

Leo:
About how different you two are, and that worries you, right?

Beckett:
I don't want to have this discussion right now.

Leo:
And those differences that are so charming now, they may end up just pulling you apart.

Beckett:
Who are you, Dr. Phil?

Leo:
No, Just a guy that may die tonight realizing that life's short. Trust me. Living your life for now makes a lot more sense than worrying about the future.
