John: Those students you butchered. They didn't just leap from your imagination. They were flesh and blood.
Shaw: Yes and they invaded my space. My world, my rules. It's a lesson you're about to learn.

Ritchie: There's only one way Shaw could pull Lily back into another world without a proper ritual.
John: It's a creation of his own design right? He built it.
Ritchie: Right, so we need a plan. Lily, she said they all ended up in different rooms of a house and we can't help her if we get killed John. Before we can find her.
John: Alright, so the first order of business is we find each other on the other side. That way we got a better chance.

John: If those kids actually made it into another realm, then they've opened gates that won't be easy to close. In current conditions, anyone can be pulled in through that gate. Not just the four that took part in the ritual.
Ritchie: Yeah well it's worse than that John. Shaw had a theory, if you're killed in another dimension your body here suffers the same form of death.

John: So this chap, Carter, he a mate of yours as well?
Ritchie: It's okay Lily, this is my colleague of sorts; John Constantine.
John: I'm just trying to piece together what happened to your mate last night.
Ritchie: It's alright, you can answer his questions. I am confident my associate's not going to get you in trouble.

Manny: Wow, self pity parade. Is this what you do when you're left to your own devices?
John: What's the point in having a mirror that shows you the past if you can't wallow in it?
