Beauty and the Beast Season 1 Episode 13

Catherine: Alex, you were his first love.
Alex: Everybody has a first love. Sometimes we outgrow them. He has.
Catherine: Why do you say that?
Alex: Because Vince always does the right thing. Like making up for leaving me. Even if his heart isn't in it. And because I'm not the one he loves.

Vincent: Alex, come on. Someone may have come to you and said they can help, but do you really think I would live my life like this if I had any option?
Alex: I think you have someone in your life who finds it convenient to keep you trapped. So they don't have to share you. But they're not helping.
Vincent: You mean Catherine?
Alex: She doesn't want to see you better.
Vincent: No, she wants to help me. Okay? And even if I don't change, she accepts me for who I am, and that is why I trust her.

Tess: (about the flowers) Secret admirer. I read the card.
Catherine: You can't read someone else's card.
Tess: Well, I did. So?
Catherine: I don't know who they're from.
Tess: Oh, come on. There was the mystery date to the wedding who cancelled, the guy last week who ran back to his ex, now this. You're either having a very serious relationship or a very serious psychotic break.

J.T.: Brutally honest, I kind of get where she's coming from. Catherine doesn't exactly wear her heart on her sleeve, then she opens up and wham, you're MIA with your ex-fiancée. Not a huge surprise her trust is running on empty.
Vincent: She knows I'll always be there for her.
J.T.: Knowing you'll always be there to rip someone limb from limb in a pinch is a little different than knowing you're not going to start playing Ice Castles with the next hot chick who comes along.
Vincent: Okay, thank you, you're really not helping.

Alex: Can I ask you something?
Catherine: Yeah.
Alex: How can you just put yourself out there like this for him? Knowing what he is.
Catherine: He saved my life. And that's all he wants for you, too.
