Izzy Lightwood: How did you get Magnus to let Jace leave?

Clary Fairchild: Traded him for Alec.

(Isabelle looks mildly alarmed.)

Izzy Lightwood: Not permanently?

Jace Herondale: No. Just for a few hours. Unless I don't come back. In which case, maybe he does get to keep Alec. Think of it as a lease with an option to buy.

Izzy Lightwood: Mom and Dad won't be pleased if they find out.

Simon Lewis: That you freed a possible criminal by trading away your brother to a warlock who looks like a gay Sonic the Hedgehog and dresses like the Child Catcher from Chitty Chitty Bang Bang? No, probably not.
