In an unmissable emotional finale, this week’s Casualty will mark the departure of clinical lead Dylan Keogh, the brilliant, gruff, endlessly complex doctor who’s defined Holby’s soul for over a decade.
Titled “A Softer Side,” the episode promises to show Dylan not just as a doctor — but as a man saying goodbye on his own terms.
⚓ Houseboats, Dogs, and Loose Ends
As Dylan clears out his locker and begins preparing to leave Holby behind for a remote medical boat project, the memories start to flood back:
-
Faith catches him feeding a stray dog outside and quips: “So you’re not a total grinch, then?”
-
Rida leaves a post-it on his office door that reads: “For the record, you were always my favourite nightmare.”
-
Iain avoids a proper goodbye — but slips Dylan a keyring with a dog tag: “Less sarcasm, more sunscreen.”
💬 A Farewell With No Fuss (Almost)
Dylan insists on no party. No cake. No speeches.
But Siobhan corners him in the stairwell and delivers one anyway:
Siobhan:
“You didn’t hug people. You didn’t flatter anyone.
But you showed up, every time.
And we were all safer for it.”
😢 Final Scene: A Quiet Exit
Dylan walks out past the ambulance bay. He pauses briefly, looks back once, and gives the smallest, almost imperceptible nod. Then he steps into a cab with a duffel bag slung over his shoulder.
The camera lingers on an empty corridor.
A cup of tea grows cold on the desk.
🔮 What’s Next?
-
Dylan is headed to a floating remote medical clinic — no wifi, no phones, just medicine.
-
Faith receives a letter weeks later, handwritten, about how “the silence isn’t so bad after all.”
-
There’s talk he may return in a guest arc down the line — especially if Holby finds itself in another crisis.
