Meanwhile, as Lola grows closer to Lord Julien, she gets increasingly suspicious that he is going to betray her. - The CW
Cortenza de' Medici: I always enjoy his company. As I know he always greatly enjoys mine.
Queen Catherine: Except for the day he left you in tears when he decided to marry me. Oh life is full of surprises isn't it.
Prince Francis: I am in your debt, Leith Bayard.
Cortenza de' Medici: I remember you as a child. So talkative and free with words.
Queen Mary: Catherine could i have a private word with you
Cortenza de' Medici: Oh there your go. More words.
Queen Catherine: You're a queen. Don't beg.
Leith Bayard: No one risks their lives for some lord's strategy. We do it for those we love.
Lord Julien: If I’m careful with my words it is only so you understand. You have a strength you have yet to realize.
Cortenza de' Medici: And I don't mind getting the heel of my shoe bloody.
Queen Catherine: I suppose innocence is all relative. I wonder how long Mary's will last. Because once it's gone, it can never be reclaimed.
Prince Francis: A wise man once told me, yesterday as a matter of fact, that we fight for those that we love. I’m just like you. I want to go home. There must be someone that you’ll fight to see again.
Leith Bayard: There’s a woman. But it could never work.
Prince Francis: I have lost good men and I’m not prepared to lose anymore, specially if I can help it. Live Leith Bayard, LIVE.
John Prevo: They're monsters.
Queen Mary: Indeed they are. But they’re my monsters now.

- John Prevo's only reason for not double crossing Mary was that he didn't want people to know his loyalties could be swayed so easily. However he still brought Catherine the head of the person she thought set up her kidnapping. So to anyone else except Mary, it appeared John Prevo killed his original dealer.
