Katarina Rostova is the mother of Elizabeth Keen.
Katarina Rostova is a former KGB agent who used to work in Foreign Intelligence and the mother of Elizabeth Keen. According to Red, when the Soviet Union was collapsing, Constantin Rostov took Liz from her and fled. Katarina gave up everything to follow her husband and her daughter. When she finally found them, she and Constantin were arguing with her pleading to come back and to be a family again. The argument escalated into a physical confrontation in which resulted in Liz shooting her father to protect her mother. However, due to Liz's trauma and Red's evasive answers, it is not clear what really happened that night.
Constantin told Elizabeth that she and Raymond had an affair which she at some point ended it. Upset, Raymond allegedly took Liz from her parents.
Depressed that the child she adored killed the only man that she ever loved, Katarina was never the same again. Two months later, she went to Cape May, New Jersey, left her clothes on the beach and walked into the sea.
While her present fate is unclear, both Red and Sam Scott told Liz that her mother died. Most people in the intelligence community believe that Katarina Rostova never existed. Several CIA agents viewed her as a Soviet Mata Hari whose career had been glorified for propaganda reasons. She was a myth and had been a cover identity for numerous female Soviet operatives. However, there have been signs that Katarina Rostova faked her own death. Anton Velov was tasked with hunting down Katarina Rostova and tracked her down to a hotel in Prague. When Anton came, he found that Katarina left the hotel in a hurry but missed to take the picture of Masha with her. In "Drexel", it was revealed a painting was commissioned titled "Rostova".
In "Mr. Kaplan: Conclusion" it is revealed that Reddington was involved in Katarina's fate. Dembe comments that he doesn't think Elizabeth will "ever be ready to learn about what you did to Katarina". Red is determined to make sure Liz never learns the truth of what happened to her mother, believing the truth will damage her beyond repair.
She is briefly mentioned by Peter Kotsiopulos when Liz searches for the truth and finds out that Katarina is her mother. It is also known that she was a KGB Russian Spy, wanted by the FBI.
