Debailly continues to be tailed by the Russians. The DGSE meet an Algerian with information about Cyclone. They decide to recruit Nadia; Marie-Jeanne realises that Debailly has not told her the full truth, and confronts him. She also helps Marina compel a second colleague to refuse the Iran secondment, and teaches Marina a lesson about not getting close to her contacts. Debailly continues to be interrogated by the CIA in flashforward; it is revealed that Dr Balmes works for the Americans.
