Claire: They say the definition of insanity is doing the same thing over and over and expecting a different result.
Jamie: Well, I dinna ken who 'they' are Sassenach, but I'll wager 'they' have traveled through time.

Claire: So, will I be allowed to join you at dinner tonight?
Jamie: Aye. My grandsa isn't opposed to a little decoration at the dinner table, as long as the decoration doesna speak.

Claire: Before we go, there's something I need you to do. Say thank you to Laoghaire.
Jamie: Thank you for what? For not having you arrested in the last few days?

Jamie: Please tell me I'm nothing like him, Sassenach.
Claire: I'm afraid I may have seen a similar turn of mind.
Jamie: We may have to rethink our decision not to lie to one another.

My name is Jennifer... and I'm an addict.

Jennifer

Now you want to help? You left me in boarding school half a world a way after Dad died!

JJ (in dream)

You need to learn to do what we ask and only what we ask. There is no deal.

Roman

I'm serious. There's this thing inside of me and sometimes it takes over.

Chase

JJ: I'm just here as a friend.
Rory: Why don't I believe that? Maybe it's because the minute you dressed up as a cop you decided to cut me off.

Eduardo: You and JJ are getting... close.
Gabi: Let me guess. You don't like that one bit, do you?

Steve: No biker gang uses it.
John: No, they're into angels and devils and snakes.

You came to me an orphan. That's all you'll ever be.
