 After the second season, Gulya Nizhinskaya and the rest of the crew  had a conflict (although it is impossible to know its exact nature,  because the story is told differently by the actress and the  production crew), she left and Vikas friend was recast. But to  avoid fans to take it badly, the newly recast friend was made a new  character. Thats why in the beginning Vera is Vikas best friend,  but when her another best friend Galya resurfaces, Vera is nowhere  to be found.
