Mozer did take a half year sabbatical and she was at Skate America with T/M. T/M's main coach, who worked with them on the ice on a day to day basis, was Andrei Hekalo. T/M said they felt they need to make a change in order to develop and switched from Hekalo to Trankov. Nina Mozer is a sort of a team manager, an overseer. Robin was never with them every day, rather he goes to Moscow or Sochi for a few weeks at a time. He was at Sochi with them at least in the beginning of autumn, so as far as I can see he is still collaborating with them.
