Casualty fans - us included - were in bits when Cal died after a plot twist that none of us would have predicted. A plot twist that none of us wanted!
It seemed a strange move for a show to do away with one of their most popular characters. Who do they think they are, Line of Duty?
Now, it seems handsome actor Richard Winsor, who played the handsome medic, wanted to head for pastures new.
According to reports, he is heading to Hollywood to be with his stunning model girlfriend Gabriella Kuti - and to try and launch his career stateside.
“Rich has been constantly jetting back and forth between the Casualty set in Cardiff and the US to visit Gabi, who he has been dating on and off for several years now," a so-called source apparently told The Sun.
“He has found it exhausting maintaining such a long-distance relationship while holding down a demanding job.
“He thinks that by moving across the Pond he will be able to have a top acting role as well as see Gabi regularly.
Rich has been constantly jetting back and forth between the Casualty set in Cardiff and the US.
“Rich loves the LA lifestyle and has always had his heart set on doing something on the big screen or the stage, so this could be the first step to a huge career.”
It seems Gabi was just as upset as the rest of us watching Cal breathe his last on Saturday, judging by her cute tweet...
The doctor was stabbed to death by an angry relative who believed his father’s passing was the fault of striking doctors.
Killer Scott Ellison had been planning to target Cal’s brother Ethan (George Rainsford), but Cal stepped in to try to stop the attack and ended up being fatally injured himself.
His colleagues tried desperately to save his life but he had lost too much blood.
Viewers found the storyline particularly tragic as the brothers had only just put aside their love rivalry over fellow medic Alicia (Chelsea Halfpenny).
The BBC drama had trailed that tragedy was in store but had placed a red herring with Lily (Crystal Yu) suffering an accident in the car park.
Meanwhile, the serial drama has revealed it will be airing a special episode filmed in a single take.
Filmed in real time, it will be a fly-on-the-wall look at daily life in the emergency department.
The ambitious episode will be at the end of the 30th series to celebrate the anniversary of the monumental run.
Called 'One', it will focus on nurse Duffy as she shows two teenage girls, Chloe and Diamond, who are on work experience around the hospital. It's set to show the highs and lows of the running of the ED.
Although it won't be shown to viewers live, a single camera will follow Duffy around and keep running throughout, meaning it's as close to live as you can get without actually being live, and there is no room for error.
We'll even see them attempt to move into an ambulance seamlessly, and there's set to be 360 degree shots involved, with sound coming from 40 hidden radio microphones.
Cathy Shipton plays Duffy and she's spoken about how excited she is to lead this very special episode.Read more: EastEnders fans outraged as loyal character sacked
"It's so exciting and nerve-wracking to be working on this episode and unlike anything any of us cast or crew have ever attempted.
"It's a brilliant fly-on-the-wall episode in real time, placing nurses central in the storyline. It will become a classic Casualty."
Series producer Erika Hossington said: "This special episode will give the audience a unique insight into an hour in A&E. It will be an intense, emotional hour in which staff and patients are faced with life-changing events.
"We want to reflect the front line in its unedited, rawest form, and this one shot episode, with a brilliant script from Casualty creator Paul Unwin, has given us the opportunity to do that."
The show had previously ruled out a completely live show due to the constraints of not being able to do a traditional Casualty stunt.
But with cast and crew all keen to do something a bit different, the producers promised something special.
