Siobhan McKenzie’s day from hell begins
Siobhan McKenzie faces a life and death dilemma as her husband fights for his life…
As the episode opens for Siobhan (Melanie Hill) it’s revealed that she and her husband, Rich Walker (Michael Keogh), are living together in their family home, although the cheating firefighter is in the spare room.
Dropping Siobhan at work, Rich tells the acting clinical lead that their son Ben caught him leaving the guest room and insists that they need to tell their grown-up children that they’re splitting up.
Siobhan reluctantly agrees, although she’s still deeply hurt that he betrayed him with consultant Stevie Nash (Elinor Lawless), and suggests they break the news later that evening. But there’s no time to dwell, as a call comes in about a plane crash outside Holby airport and a major incident is declared…

A slight thaw
Although it’s all hands on deck at the hospital as casualties come pouring in, Siobhan and Stevie are unable to put their differences aside during the life and death shift.
That is until there are reports of a massive explosion at the crash site and an unidentified firefighter is admitted to the ED with catastrophic burns.
Both women come together in a moment of utter relief when it turns out not to be Rich – but their camaraderie doesn’t last long!
Warning – major spoilers beyond this point.

Siobhan’s double-edged dilemma
An injured Rich is admitted to the ED in a fragile state…
“Rich is brought in suffering from smoke inhalation and you can see how much Siobhan loves and adores him,” says Melanie Hill in an exclusive interview with What To Watch. “What makes everything worse is she goes with him for his CT scan, thinking that he’s going to say he loves her too, but instead he asks her to, ‘Tell Stevie I love her.’”
Full interview coming soon. Check back for updates.
Seconds later Rich starts deteriorating and is raced to Resus for emergency care, leaving Siobhan with a dilemma… Will she tell Stevie, so she has time to see him before it’s too late?
What will Siobhan decide?
And will Rich survive?
