At the 2004 Skate America, shortly after Tatiana Totmianina's accident, Obertas fell out of an overhead lift, a hand-to-hand lasso lift, but Slavnov managed to catch her to prevent her head hitting the ice. The pair won silver at the 2005 European Championships and were fifth at the World Championships. During the 2005-06 season, they were fourth at Europeans, and then finished eighth at both the Olympics and Worlds.
