On 8 September, she said she would resume light on-ice training in a few days. Commenting on her switch to pairs, Marchei stated: "At the beginning practicing pairs was just to do shows or stuff like that, but then it was something that got to me. It's crazy. I still do single programs at shows, but it is strange, I'm looking around, where is he?"
