Beauty and the Beast Season 1 Episode 7

J.T.: So, just out of curiosity, when you were armed with a loaded tranq gun that would have prevented exactly what happened in the tunnel, why not use it?
Catherine: Look, Vincent was my only hope of saving Evan. I took a chance.
J.T.: You may have saved Evan, but you didn't think about the price Vincent would pay.

Catherine: (in the subway tunnels) Anything?
Vincent: Other than bad memories from the last time we were down here? No.
Catherine: I'm alive because of you.
Vincent: And I would do it again. It just doesn't make taking a life any easier, that's all.

Catherine: (cheery) Good morning!
Tess: Handbook chapter 3: try to not look giddy when approaching a murder scene.
Catherine: I seriously doubt I look giddy.
Tess: We'll get back to that.
