All Saints - Season 9 Episode 5 The Things We Do

A Work Cover claim has Charlotte and Nelson's replacement, Deanna, at loggerheads when an investigator for the insurance company insists their patient is a fraud. A middle aged man presents with stomach pain that is difficult to diagnose. No one can quite believe the cause when it is eventually located. Deeply concerned about Nelson's frame of mind since he quit his job in the Emergency Department in the middle of his shift, both Frank and Von decide to pay their former co-worker visits. But it's safe to say that Frank and Von receive anything-but-friendly receptions from Nelson, who is still outraged that his colleagues wrongly assumed he had begun drinking again. Deanna shows a side to her that Jack has not seen before.
