Michelle permanently fell out with Ruth after she caught her in bed with her half brother Adam. Before this their colleague Daniel Granger witnessed Ruth pretending and declaring to be Michelle and this had led to a patient nearly dying of a heart attack. When Daniel warned Michelle of Ruth's strange antics, Michelle confronted Adam about his relationship with Ruth. She discovered he had been seeing her secretly and that Ruth had been stealing her possessions including her clothes for months. Initially, Michelle thought Adam was defending Ruth and that he knew that she was her friend, but he insisted that he had no idea of what Ruth was actually doing, that he loved her more than Michelle which was why he offered that Ruth should be referred to a mental health institute, where she was later sectioned. Due to this, Ruth stole and took away Michelle's pendant that Michelle's dad had given her when she was a child. Michelle was furious to learn that Julia Parsons was letting Ruth stay at her place after her release from section. She decided that she should leave but Heston Carter and Cherry managed to persuade her to stay. Heston told her that Ruth wouldn't be allowed back to the surgery. However, Melody determined that Ruth was ready to return to work which, as predicted, made Michelle furious.
