Isabel reveals her true allegiance as Slade makes his move on Oliver, abducting Thea and putting Oliver's secrets at risk. Meanwhile, Roy grows increasingly impatient with Oliver, who he believes put Thea in danger by forcing Roy to break up with her.
Roy: What's the worst that could happen if I just told her the truth?
Felicity: Well, I told a guy the truth and he got struck by lightning. To be fair, probably won't happen again, statistically.
Felicity: Do you remember where you put your business suit? Or do you keep it in a cool glass case, too?
Peter: And what gives any of us the right to decide one's life is more valuable than another?
Anatoly Knyazev: He is tied up. We are not.
Moira: And how is Ms. Rochev these days? Still angry that Dorothy dropped a house on her sister?
Sara: Can you remove the explosive?
Anatoly Knyazev: Certainly. Without it going off, eh. Less certain.
Moira: I've told you that these lies were to keep our family safe; to keep us all together, but that was the biggest lie of all. And I told it to you, to Thea, to myself. Because I was too weak to face any kind of truth.
Oliver: What's happening now isn't your fault.
Moira: From the moment your children are born, you worry what the world might do to them. But you never stop to think what you might do to them. that we could be our own worst enemy.
Sara: Ollie! What did you to do him?
Slade: Not enough.
Slade: Don't worry. I am not here to harm you.
Laurel: Go to hell!
Slade: All in good time, I'm sure.
Moira: Still angry that Dorothy dropped a house on her sister?
