In the 2012–13 season, Davankova/Deputat won silver at their first JGP event in Lake Placid, New York. At their second event, in Zagreb, Croatia, they took the bronze and qualified for the JGP Final in Sochi, Russia, where they won the silver medal behind Lina Fedorova / Maxim Miroshkin. By that time, Davankova had grown to 1.55 m. Davankova/Deputat finished seventh in their second appearance at the 2013 Russian Championships. In January 2013, Davankova injured her leg at a training session, resulting in the pair withdrawing from the 2013 Russian Junior Championships. She was on crutches for two weeks. In late March, Deputat injured his right leg and decided to undergo a meniscus operation.
