When Gibbs entered the room across the street, he realised he was too late, the younger agent lay dead in the idle of the room. His throat had been slit and the room was covered in blood. He heard the tread on the stair a fraction too late and turned gun drawn as the young man was already through the door his own gun drawn.
"Who are you?" The young man asked
"You first?" Gibbs replied.
"You didn't do this?" the man told Gibbs in English, before quickly returning to Russian "I know who you are"
Gibbs didn't register any reaction, he raised his gun and shot the man in the shoulder. "Tell me who you are" he stood over the man.
"Callen, CIA"
Gibbs deposited the CIA agent on the spare bed, he closed the curtains and started dressing the wound.
"This the wife's house?" Callen asked him
"Yeah" Gibbs gritted his teeth, he'd been stupid, he'd been careless, and it was Stephanie's fault.
"What happened to the Consulate girl?" Callen asked
"I shot her"
"Must have been your day for it" Callen quipped, then looked at him "You didn't know she was a spy?"
"NO!" Gibbs snapped
"Yeah, didn't figure in with what we knew about you. Stress of your wife's miscarriage, made you…"
"Do you know everything about me, kid?" Gibbs snapped again.
"What I need to, your mission has been compromised"
"You think?" Gibbs kicked the door.
"Not by you, Natasha, she was good, clearly but she got nothing from you, it was your other agent."
"Bullen?" Gibbs thought back to the young agent, the bloody mess on the apartment walls, he thought for a moment then breathed out "Probie mistake", then he laughed "Christine Keeler".
"CIA, think you need to get out of Moscow"
"I need to get out of my marriage" Gibbs grimaced.
