    Finale

    Anya and Masha, shaken by their mother's story, try to find common ground. Anya admits she fears for Vadim and is willing to risk everything to find him. Masha proposes a plan: use Roman's connections to obtain information about missing persons. Roman, touched by their unity, agrees to help. Through SBU channels, they learn that Vadim is alive, but in a war zone. The sisters decide: until they know his fate for sure, they will stick together.

Anya receives an anonymous message with coordinates of a location where Vadim may be. She decides to go there, but Masha dissuades her, fearing for her nephew's safety. Roman, seeing Masha's hesitation, threatens to expose her "unpatriotic position" to the press. A crisis is brewing in the family: Anya feels like a prisoner, Masha like a hostage to circumstances. Lyubov Pavlovna, realizing that her daughters are on the verge of a breakup, tells them the truth about her past—how she once lost contact with her own sister because of ideology.
