By the time Jean came on board, the close nit atmosphere of Motown was almost gone. I doubt any of the other artists mistreated her when they did encounter her, and I'm sure paths did cross. Everyone at Motown appears to have been competitive. They all wanted to be on top; wanted to outdo the others. I think Diana's behavior at times allowed friendly rivalries to become a bit hostile. By the time Jean joined the group, I don't think most of the other artists had time to be concerned with Jean or the Supremes.
