My father needed a spy in the English court, and I fulfilled that need, and I did it very well. Until now, apparently. Not even Phillipe de Clairmont thought to factor in time travel when he gave his orders.

Matthew

Francois: I hope I wasn't unwise to place my trust in you.
Diana: You weren't. I already knew he was Catholic. He told me.
Francois: Well, if you'd bewitched him, he would tell you anything.
Diana: Listen to my heartbeat, Francois. I will not tell a soul what I've seen up here, I promise. I suspected that he was a spy. I just, I hadn't put it together until now. He's identifying Catholics, betraying his own people, his faith.

Diana: I always told my students cities of the past would have smelled awful.
Matthew: Trust me, some parts do.

Matthew: I've never run scared from anything in my life. I simply won't take risks where your safety is concerned.
Diana: Well, I'm not staying locked up in here. So either you find me that witch, or I will go out there and find her myself.
