1x13 - Snowdrop

Nadya informs Irina that she can't find the surveillance's CD so that she can show it to Rita. Irina claims that she has no idea about the same, but then Nadya asks her as to how she managed to create a CD, if she had no clue about it. An argument breaks between both of them, but then their father intervenes and asks them to get dressed to meet Rita, as she is awake now. Irina has an intense inner monologue in which she convinces herself that Rita mustn't have seen her, as she was in shock.
