Stevie Nash starts a sizzling affair

The temperature rises for Stevie Nash (Elinor Lawless) when she makes a fateful decision in Casualty this week.

Viewers are aware that Stevie’s love interest, firefighter Rich Walker (Michael Keogh), is married to Holby ED clinical lead Siobhan McKenzie (Melanie Hill) — and this week consultant Stevie Nash unwittingly gets closer to her boss’s hubby!

Lustful sparks flew last month when Stevie met Rich at a car crash. Since then, he’s been constantly texting her to meet up!

Now, after a tough shift and some encouragement from an oblivious Siobhan, Stevie meets Rich at a bar. The chemistry between them is palpable and they share a passionate kiss!

“Rich knows that Siobhan’s a nurse and Stevie’s a doctor, so you could put his actions down to stupidity or brazenness!” says ex-Emmerdale star Michael Keogh in an exclusive interview with What To Watch. “I don’t think he does it deliberately. He just can't help who he has feelings for!”

Also in Casualty this week…

In an unusual step to the casual onlooker, Stevie turns to Dylan Keogh (William Beck) for relationship advice. The casual onlooker in this instance is psych nurse Sophia Peters (Kellie Shirley), who scoffs at the notion of Dylan being in a relationship. 

Is all her negging covering growing feelings for the brilliant doctor?

Jodie Whyte (Anna Chell) is literally left holding the baby on her day off when Teddy Gowan (Milo Clarke) receives a call from Jacob Masters (Charles Venn) asking him to check up on his house. 

It turns out that Jacob has been robbed — and the news is about to get a whole lot worse. His missing son, Blake, is the person who burgled him.

Why is Blake so desperate that he’d steal from his own father? It’s a question that troubles Jacob deeply and leaves him both furious and frightened.

Meanwhile, after a day of babysitting baby Carter, Jodie panics at the thought of a life of domesticity and takes action to shake up her circumstances, which could have painful repercussions for Teddy…

Elsewhere, the mystery surrounding Cam Mickelthwaite (Barney Walsh) and Jamie Cleveland’s (Ryan Hawley) shared past, develops shockingly…

When Bobby Morton (Ryan J Mackay, Shetland) arrives at Holby ED Jamie turns to Siobhan and reveals that he has a restraining order against the young man, dating back from his days as a youth group volunteer… The youth group that Cam attended as a young teenager. 

Later, when Cam spots Bobby at the ED, he panics, and the details of Bobby’s accusations come to light, leaving viewers questioning who is telling the truth — Bobby or Jamie?
