Valentine walked through the Silent City with Maellartach, swiftly killing the Silent Brothers he met along the way. When he got to the prison and looked into one of the last cells, he saw his foster son lying on the floor, "Jonathan."

"Is anyone there?"

"Surely you recognize your own father, Jonathan." The rune Valentine had drawn on himself to help see in the dark was hard pressed in this darkness, though he watched as Jonathan tried to stand and slipped, falling hard on the floor. He took his witchlight out of his pocket, "Are you hurt?"

"That thing, where is it?" Jonathan asked.

Valentine took in the way Jonathan's hand was limp in the manacle, the bruising around his wrist, "You are hurt. Who ordered you locked up here? Was it the Clave? The Lightwoods?"

"It was the Inquisitor." Of course, Imogen Herondale would punish Jonathan for things he had no knowledge of, simply because of association. Valentine felt anger that Jonathan-who went by Jace now-was mistreated for no reason, and amusement because Imogen surely didn't know that Jonathan was her grandchild, and she was causing his current suffering.

In moments of weakness, Valentine wished that this Jonathan was his biological son and that he had never done what he did to Jonathan while he was in Jocelyn's womb. He wondered if Jocelyn would have left if their Jonathan was not part demon.

Squatting, Valentine spoke again, "The Inquisitor and the Clave are one and the same. And the Lightwoods should never have allowed this to happen. I would never have let anyone do this to you."

"Did you come down here to kill me?" Jonathan had hunched against the wall, looking frightened in a way that Valentine hadn't seen in him since he was a small child.

"Kill you? Why would I want to kill you?"

"Well, why did you kill Jeremiah? And don't bother feeding me some story about how you just happened to wander along after he spontaneously died. I know you did this."

Wondering why he ought to have to explain himself to a child, Valentine decided to just be honest with the boy, "I did kill him, and the rest of the Silent Brothers as well. I had to. They had something I needed."

"What? A sense of decency?" The look of defiance was at odds with the obvious pain Jonathan was in, and Valentine decided to not let the jab sink in. Of course, Jonathan would have changed in more than half a decade of living with the Lightwoods, but Valentine's more paternal instincts hoped he wasn't so snarky to Maryse and Robert.

After he left, hearing Jonathan's plea, "father, please" echoing in his head, Valentine reflected on who he had just talked to. Jonathan was not the same as Valentine remembered. He was a warrior now, stoic and brave. The traces of the golden little boy were gone, replaced by a trained and capable Shadowhunter. Valentine wondered about the time between, wondered if Jonathan still played the piano, still loved so fully without restraint.
