Varvara

Varvara is the mother of Lucya, Pavel, Kirill and Viktor. She is the character from that family that we know the most about. Kaz Weiss is her step-daughter, who was married to her only daughter - Lucya.

Biography
Not much is known about Varvara's early years, but we are told what happened after the accident at Chernobyl. Her husband died in the midst of all the chaos and left her with four children (two of them babies) and with nothing but a house. Some officers come to ask them to leave the area but Varvara refuses, saying that the house is all they have left and they stay.

Years later her children are working for the government, taking care of the reactor and making sure it doesn't happen again. They are even given special medicine for when they are around radiation too much. After Mr. Cruz fires missiles at their house, they have nothing left. Kaz goes to live with Lara and Sam in London, but nothing is known about Varavara and Pavel's current residence.

Personality
Varvara is a strong and brave woman, who will do anything to protect her kids. She gets payback on their murderers, with Lara's help.

Trivia

 * Varvara and Pavel are the only survivors of their family after Cruz's attack (if we exclude Kaz, to whom they do not have a blood bond to)
 * She is shown to own guns (presumably Kalashnikov) as she tells Lara, just before the attack
