Henrietta and her "handler" Jose, members of Section 2 of the Social Welfare Agency, which handles covert government actions, are ordered to a site to acquire a witness. In a flashback, Jose recalls how he found Henrietta in a hospital after her family had been killed. He had her nursed back to health, fitted with cybernetics, and trained her to be an assassin. In the present, he approaches the armed group surrounding the witness, but one of the men's threats against him causes Henrietta to start viciously attacking, and she dispatches the men inside the room.

#2 - A Day in the Life of Claes
Season 2 - Episode 8
Claes has dreams of her time with Raballo, but can't seem to remember who he is, which distresses her. However, she keeps her emotional distress to herself, and continues to follow her daily routine of study, piano and gardening, as well as being examined by Section Two's science team. Jean, concerned about how much Claes recalls, has her watch a nature video that recalls the fishing trips she and her handler would take; this serves as something of a trigger for Claes, who goes wandering through the firing range, and seems to remember Raballo's name. At the end of the episode, she and a new cyborg, Beatrice, find a meteorite in Claes' herb garden, and the song Scarborough Fair is played as she reminisces over what she can remember of her mentor.

After Henrietta finishes tea with Triela and Claes, who are supportive of her despite her mission's failure, Jose gives her a coat and asks her to join him on top of the main building. Once there, he shows Henrietta the stars through a telescope for the first time, noting that he wanted her to look upon the sky with something other than a rifle scope.

Olga and Priscilla have also headed to Milan to check up on how Angelica is doing and Marco drafts them into helping with the mission at hand. Trouble arises, when it appears that Angelica is suffering from an addiction to her conditioning pills, as she breaks Priscilla's arm due to the withdrawal symptoms she's suffering from. Priscilla manages to convince Marco not to tell Jean about what has occurred, and to let Angelica continue with the mission. Marco relents, and the team ends up capturing one of the Cleaners used by the PRF after a successful ambush by Angelica, Marco, and Rico.

Priscilla, feeling sorry for Angelica, offers her a ride back from the firing range on her Vespa, and the two become much closer, despite Angelica's continued memory loss. Meanwhile, Marco's ex-girlfriend, Patricia, is approached by a reporter named Leonardo Conti, who claims to know a shadowy truth about the Social Welfare Agency, and wants Patricia to help him investigate it. Driven by concern for Marco and a growing distrust for the Italian government, Patricia agrees, but Leonardo turns out to be a PRF undercover agent and takes Patricia hostage.
