Cochise refuses to spy for DGSE within IS, wanting exfiltration. Duflot agrees, if Cochise can free Debailly. Before he can return, Duflot is shot by one of Cochise's men; he is taken to hospital but later dies. Cochise obtains custody of Debailly. Meanwhile DGSE identify that Mossad plans to use Marina to infect the Iranian nuclear programme with a computer virus, which will subsequently allow them to disrupt it, via the seismic monitoring system linked to Baku. Marina panics again when she discovers the Iranian connections of her new security manager, and tries to flee but is intercepted and reassured by the Mossad agent.
