City of Ashes Part 1, Chapter 5 Summary

How It All Goes Down

Jace is in the prison of the Silent City. It's silent. And dark.
All of a sudden, it's no longer silent. A harrowing screech splits the air.
Something crashes into the room of cells. Jace sees it's one of the Silent Brothers, Brother Jeremiah, who stumbles into the room, screams, and dies.
Jace is terrified at whatever must be killing the Silent Brothers, who he thought were invincible.
That whatever slinks into the room, "huge and dark and formless" (1.5.19) and lunges at him. Uh oh.
Meanwhile, Clary is smooching Simon when she gets a text message that causes her to grab her coat and get ready to leave.
In the Silent City jail, Jace has fainted.
When he wakes up, his father, Valentine, is standing on the other side of the bars.
Valentine reveals that he is there to steal Maellartach, the Soul-Sword.
He tries to tell Jace that he's not an evil bad guy, but Jace doesn't quite believe him. Huh. Wonder why!
There's a noise up above, so Valentine flees, telling Jace he can find him when he wants to find him.
Above ground, Clary rushes to the Institute to get Alec and Isabelle.
It was Isabelle who texted her that Jace was in jail.
They decide they need to go visit him to talk some sense into him, get him to stop aggravating the Inquisitor on purpose.
While they're talking the Institute gets a message that the Silent City has been attacked.
The three decide they have to go rescue Jace, but before they go, Isabelle decides she needs to give Clary some Marks.
