Jace Herondale: There is no chance I’m going to let you do this, Alec. I’ll wrestle you to the ground if I have to.

Magnus Bane: While that does sound tempting, there is another way.

Jace Herondale: What other way? This is a directive from the Clave. I can’t just weasel out of it.

Magnus Bane: But I can. Never doubt my weaseling abilities, Shadowhunter, for they are epic and memorable in their scope. I specifically enchanted the contract with the Inquisitor so that I could let you go for a short time if I desired, as long as another of the Nephilim was willing to take your place.

Alec Lightwood: Where are we going to find another—Oh… You mean me.
