Love sick Ethan?

Ethical loathing: Why is Ethan determined to ruin his career?

Doctor Ethan Hardy’s unhealthy attachment to patient Effie Laurence becomes even more complex this week! Having recently lied to medical colleagues and doctored Effie’s patient notes in order to get her on a cystic fibrosis trial, Ethan (George Rainsford) has already crossed countless ethical lines.

This week Effie (Abigail Hardingham) comes to him for advice on whether or not she should go through with the trial. For once, Ethan manages to give her neutral advice.

Later, however, when distressed Effie’s admitted to the ED with breathing difficulties, will Ethan be able to hide his growing feelings and remain impartial?

Custody battle lines drawn?

Snatches of junior doctor Mason’s home life are revealed over the course of one particularly difficult working week, but will this explain why he’s determined to succeed no matter what the cost to others? (By ‘others’ we mean poorly patients and resident ED doormat, Rash!)

Keep an eye out for Hi-Di-Hi! star Ruth Madoc as kind-hearted patient Millie. She takes a shine to Mason, but is at risk from young medic’s inexperience and ego… (More on this below)

Mason’s Casualty guest star storylines

Ruth Madoc as kindly Millie with Mason

Easy to please OAP. Ruth Madoc as kindly Millie with Mason

Ruth Madoc guest stars in Casualty as Millie Faulkner, who is more concerned about junior doctor Mason being rushed off his feet than her own health. Millie’s brought herself to the ED at the insistence of daughter Chloe (Stella star Michelle McTernan), suffering with a chronic cough and chest pains.

After running a series of tests Mason concludes Millie’s well enough to go home. Later, however, Mason panics when he realises he’s made a basic but potentially serious mistake. Will Millie suffer the consequences?

Also this week, Tafline Steen plays patient Corina Samways. She’s admitted to the ED after a drunken fall. When Mason criticises her life choices, will she put him in his place?

Whatever your feelings on Mason, there’s no denying Victor Oshin impressively captures his many complexities.

Casualty continues on BBC1 this Saturday at 9.20pm
