New locum consultant Keira Balfour manages to ruffle Jac's feathers on Keller and she takes her eye off the ball and messes up in surgery. She later falsifies the patients record to take the blame off her and put it on Chrissie. Mark later tells her she can interview for the permanent locum consultant and after a balsy interview with Mark and Hansen she is offered the job but Michael warns her of her rash decision in applying for the job. Meanwhile, Faye's stability on the ward is questioned and later at her baby shower she throws a wobbly and then becomes violent towards a patient forcing Joseph to have her committed to a baby and mother psych facility. Elsewhere, Donna's colleagues give her a taste of her own medicine.
