Izzy Lightwood (about Simon): And now what are we supposed to do?

Raphael Santiago: Bury him.

Jace Herondale: That’s not funny.

Raphael Santiago: It isn’t supposed to be. It is how we are made. We are drained, blooded, and buried. When he digs his own way out of a grave, that is when a vampire is born.

Izzy Lightwood (disgusted): I don’t think I could do that.

Raphael Santiago: Some can’t. If no one is there to help them dig out, they stay like that, trapped like rats under the earth.
