Von's past is highlighted when a patient, Will Harrington, she nursed in a London pediatric unit is admitted to Ward 17. His memories of Von result in a lot of stirring from the rest of the staff and consequently a furious Von confronts Will, telling him she is not the person he thinks she is. Will comes to realise she may be right — he doesn't recognise this new Von at all. Besides, he does not need handholding any more — he is an adult. But, on learning he has cancer, all Will's childhood fears re-surface and Von is forced to re-enact the magic that got him through his childhood illness to help get him through this one.
