When Casualty last aired two weeks ago with Sinking Ships – Day 2 it unleashed the jaw-dropping cliffhanger that consultant Stevie Nash’s new flame, Rich Walker is married to clinical lead Siobhan McKenzie.
Remember how sparks flew when Stevie (Elinor Lawless) first met the fireman at a car crash (how’s that for a metaphor?) in Sinking Ships – Day 1?
Well, this week in After the Flood, with some encouragement from Siobhan (yes, really!), Stevie meets up with her boss’s hubby and one thing leads to another…
As of yet, neither woman knows about the other, but it’s clear that Rich is playing with fire – and we’re here for it!
Here, Peaky Blinders and Emmerdale star Michael Keogh, who joined the Casualty cast as firefighter Rich Walker last month, tells us more and teases what lies ahead in this explosive storyline…
