When her mother disappears, Clary Fray learns that she descends from a line of warriors who protect our world from demons. She joins forces with others like her and heads into a dangerous alternate New York called Downworld.

Clary Fray: You play that piano as if you've lost your only love.
Jace Wayland: Unfortunately, my one true love remains myself.
Clary Fray: Well, at least you don't have to worry about rejection.
Jace Wayland: Not necessarily. I turn myself down occasionally, just to keep it interesting
Clary Fray: This is the part where you start tearing off pieces of your shirt to bind my wounds.
Jace Wayland: If you wanted me to take my clothes off, you should have just asked.
Jace Wayland: Next time, it might be a nice idea to mention that you already have a man in your bed, so we can avoid such uncomfortable situations.
Simon Lewis: You invited him to bed?
Jace Wayland: I know, it's ridiculous, isn't it? We would never have all fit.
Clary Fray: I didn't invite him into bed. We were just kissing.
Jace Wayland: How swiftly you dismiss our love.
Jocelyn Fray: Jesus!
Simon Lewis: No, just me.
Jace Wayland: Don't tell me. You've got a drawing emergency, and you need a nude model. I'm not in the mood.
Isabelle Lightwood: Doesn't she look great, Alec?
Alec Lightwood: She looks like someone whose phone number should be on a bathroom wall.
Jace Wayland: For the record, my hair is naturally blonde.
Luke: I'm a werewolf, not a Golden Retriever.
Jace Wayland: [introduces himself] Jace Wayland, demon hunter.
Simon Lewis: Ah... Simon Lewis, Keymaster. Are you the Gatekeeper?
Jace Wayland: I have no idea what you're talking about.
[last lines]
Clary Fray: I just don't know how to look at the world anymore. I don't see street and traffic lights and cars. I see demons and angels. Everything's different.
Jace Wayland: The world's the same. You're the one who's different.
Jace Wayland: [starts his motorcycle] Don't you remember what Hodge said?
Clary Fray: What?
Jace Wayland: All the stories are true.
[they ride off together]
Clary Fray: How is being dressed like a hooker going to help me find my mom?
Isabelle Lightwood: Easy now, those are my clothes.
[from trailer]
Jace Wayland: [to Clary] You have an incredible gift and we need you... I need you.
Simon Lewis: The werewolves are here to save us. Never thought I'd say that.
[Isabelle almost chops Luke's head off with a sword, but stops in the nick of time, with the sword to his throat]
Isabelle Lightwood: I almost killed you!
Luke: [dryly] Yeah!
Clary Fray: [to Dorothea] Wait, you can see this guy?
Jace Wayland: Of course she can, she's a witch.
[pushing their way in]
Jace Wayland: Downgraded from a gingerbread house to a one-bedroom?
[from trailer]
Simon Lewis: You killed two cops!
Jace Wayland: They weren't cops!
Isabelle Lightwood: This place is full of demons.
Luke: That's impossible. The Institute is hollow ground.
Simon Lewis: No one seems to have told them that.
Valentine Morgenstern: Somebody told me that you like to play music.
[smashes Jace's head twice into the piano tangents]
Valentine Morgenstern: Johann would be very proud.
[from trailer]
Hodge Starkweather: Everything you've heard... about monsters, about nightmares, legends whispered around campfires. All the stories are true.
[from trailer]
Clary Fray: Why can I see you when no-one else can?
Jace Wayland: You're not a mundane.
Clary Fray: What's a mundane?
Jace Wayland: Someone from the human world.
Clary Fray: Well if I'm not a human then what am I?
Jace Wayland: You wouldn't believe me if I told you.
[from trailer]
Alec Lightwood: What is it about her?
Jace Wayland: She's different.
Alec Lightwood: She's going to get us all killed.
Clary Fray: This is a top.
Isabelle Lightwood: It's a dress.
Clary Fray: I can't pull this off.
Isabelle Lightwood: Well, actually with the right shoes...
Clary Fray: No. I mean, this dress is so tight, it's like a second skin.
Isabelle Lightwood: If you go looking like your mundane self we won't get within 100 feet of Magnus Bane. He's the High Warlock of Brooklyn. Stop complaining, come with me.
Clary Fray: That guy Alec doesn't like me very much.
Isabelle Lightwood: That guy Alec is my brother.
Isabelle Lightwood: [to Clary] Go, you've done enough!
Jace Wayland: Don't speak to her like that! It's not her fault.
Isabelle Lightwood: You're right, this is your fault!
Jace Wayland: Isabelle!
Isabelle Lightwood: Alec kept telling you that you were going to get hurt. That you were going to get us all hurt. Now he's the one dying.
Jace Wayland: But, we needed to get the Mortal Cup!
Isabelle Lightwood: But there are other ways to get it then getting your best friend killed!
Clary Fray: If you'd been a real dad, you'd know me well enough to imagine where the Cup is, where my deepest thoughts are taking it. You don't know the first thing about me. You're not my dad. And you never will be.
[from trailer]
Clary Fray: Shadow Hunters?
Hodge Starkweather: Half Angel, Half human. Beings of immense power, strong enough to restore balance... and protect the world in a war against evil.
Simon Lewis: So that's the famous cup everyone's talking about?
Isabelle Lightwood: A replica. But yes.
Simon Lewis: You know, Jace has got a real chip on his shoulder.
Isabelle Lightwood: You would, too, if you saw your father murdered when you were a child. If it weren't for him we'd be dead. He saves our lives more times than I care to admit. Right...
Clary Fray: Does Jace know how Alec feels about him?
Isabelle Lightwood: Is it that obvious?
Clary Fray: It's really not that big of a deal.
Isabelle Lightwood: It isn't to me, either. But it is to the Clave. I don't make the rules.
[from trailer]
Jace Wayland: [to Clary] This is about more than us.

Hodge Starkweather: Ordinary, normal...
Simon Lewis: [to Clary] You know your Mom, she gets like this sometimes...
