Isabelle Lightwood: I'm in recovery now. I'm gonna be okay.
Maryse Lightwood: I am so sorry. This is all my fault.
Isabelle Lightwood: No, Mama. It's mine.
Maryse Lightwood: I've been so hard on you. Put so much pressure. Of course you needed a release... Sometimes our angelic duty seems to... overshadow everything else. We forget we're human, too.
Isabelle Lightwood: Mom, you deserve to be happy.
Maryse Lightwood: So do you. Despite this, despite everything, I hope you don't give up on love. I hope you fight for it, like your brother.
Maryse Lightwood (to Alec): I wanted to congratulate you on the promotion. I'm so pleased to see the Lightwoods back in command. I always knew this was your destiny. When you were little, I'd find you in here, sitting behind your father's desk, writing out your own memos in crayon. Well... here you are. Your father and I couldn't be prouder.
Maryse Lightwood: Alec, we looked like fools taking in Valentine’s son, caring for him like our own.
Alec Lightwood: It was the right thing to do.
Maryse Lightwood: It was a mistake. It put our family in danger. You need to forget Jace. He made his choice.
Alec Lightwood: Do you even hear what you’re saying? If you kill him, you kill a part of me.
Maryse Lightwood: When you have a cancer, you cut it out before it destroys you. Son… Life is full of hard choices.
Alec Lightwood: Don’t kid yourself. You’re not making a hard choice. You’re saving your own ass. And unlike you, I don’t push someone away just ’cause they’re a hard choice.
Maryse Lightwood (to Izzy about Seelies): Never trust a people who can’t lie. They find much more inventive ways to stab you in the back.
Maryse Lightwood: Isabelle, we stay separate from the Downworld for good reasons. The wrong move, the wrong word… Do you think there is such a thing as harmless rebellion? Who knows what offends these creatures Maybe you told him… them… something they shouldn’t know. Maybe you trod on one of their ridiculous customs without knowing it. When someone upsets the natural order, everything falls apart.
