Fans of the BBC One medical drama Casualty are convinced that a new romance storyline is developing between Jan Jennings, played by Di Botcher, and Siobhan McKenzie, played by Melanie Hill. The speculation comes after a series of scenes that viewers interpret as building romantic tension between the two characters.
Fans spot chemistry between Jan and Siobhan
In a recent episode, Jan gently removed a black mark from Siobhan's face, holding her gaze for a moment longer than typical friendship allows. This moment sparked a wave of reactions on social media. One fan, Cam, posted on X: 'jan and siobhan ??? IM ACTUALLY A PROPHET #casualty.' Another user, Ryan Glendenning, echoed the sentiment: 'Jan and Siobhan need to get together.'
Viewer Michelle added: 'Meee they would make a lovely couple!' On Reddit, a user wrote: 'I can see the two maybe getting into a relationship or sharing a drunken kiss, especially with the scenes they shared lately.' Another commented: 'Yeah I think we are gearing up for a “more than friends” storyline.'
Characters in need of happiness
Both Jan and Siobhan have faced significant hardships. Jan has been lonely since splitting from her partner Fi, following troubles with her son Ross. Siobhan is still recovering from being raped while walking home from work. Fans believe a romance could bring much-needed light into their lives. One Reddit user noted: 'I think Jan needs some love in her life. I think she’s a bit lonely since she split up with her partner.'
Dylan Keogh's storyline takes center stage
Meanwhile, the latest Casualty boxset, titled Lethal Legacy, focuses on Dylan Keogh (William Beck) and his complicated relationships with Stevie Nash (Elinor Lawless) and Matty Linklater (Aron Julius). After discovering that Matty and Stevie were sleeping together, Dylan retaliated by reporting Stevie. The stress and betrayal are expected to cause Dylan to relapse in upcoming episodes, as confirmed by actor Aron Julius.
Discussing Matty's perspective, Julius said: 'When you’ve grown up with someone being like, “oh you’re father’s this, and your father’s that”, I think Matty has built up a picture in his mind of what alcoholism is, or what his father is. He said it to Dylan, before he knew that Dylan is his father, Matty said, “Mum binned off the sperm donor, he’s an alky”. I think when you’re faced with someone who is afflicted with those problems, you realise that alcoholism isn’t exclusive to people who are down and out. You can be at the top of your game, you can be the most impressive diagnostician in the hospital and still be afflicted with this.'
Julius added: 'I think Matty attaches Dylan’s alcoholism to his mum’s pain, and his mum not being able to achieve the things she wanted to achieve. I think at first there is a defensiveness to it, and there is a view of this is the problem, you’re the problem. It’s probably an avoidance from Matty to look at himself and look at the problems and the issues that he needs to face professionally and personally, but I think at first there is a definite connection to his mum. There is also an understanding that Matty goes on with Dylan to be able to bring these two things together.'
