Who is Andrius?

Andrius is a teenager taken prisoner alongside with his mother and among the passengers Lina meets during the train ride to the working camp. Andrius was the son of a military officer who disappeared just like Kostas did. To save him from being separated from her, Andrius’ mother lied to the NKVD officers and convinced them that her son was mentally disabled. Andrius becomes something akin a mentor for Jonas and helps the young boy adapt to the new environment even though his methods are frowned upon by Lina. Andrius and Lina enter a relationship around Lina’s birthday and they become close to one another. Andrius began bringing them food or wood and when the two are separated they promise to find one another again one day. Andrius suffers because his mother agreed to have sex with the NKVD officers to save herself and her son and Andrius despises those who look down on her because of it. The epilogue reveals that Andrius and Lina meet again and that they eventually got married.
