Fans of hospital drama Casualty have been complaining of broken hearts following a shock death in the programme.
Cal, played by Richard Winsor, was stabbed to death by an angry relative who believed his father's passing was the fault of striking doctors.
The killer 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.
Viewers found the storyline particularly tragic as the brothers had only just put aside their love rivalry over fellow medic Alicia (Chelsea Halfpenny).
One viewer tweeted: "Cal dies trying to save his brother. Oh lord. I'm devastated."
Another shared: "Probably one of the most affecting episodes ever of #Casualty. Bye Cal."
Fans of the programme began sharing their devastation at the scenes in which Cal bowed out.
One tweeted: "Seeing Ethan breaking down over Cal's body pushed me over the edge. Heartbreaking."
Another fan wrote: "Bawling my eyes out at #casualty what a heartbreaking ending. Can't believe Cal is gone."
The episode was traumatic for viewers who had grown attached to the character.
A fan tweeted: "Heartbroken at Cal dying tonight. I can't tell my Daughter. How quick can we get counselling on the NHS."
Someone else shared: "Literally proper ugly crying. on a train. people watching me. I have no shame. Cal has broken me."
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.
A viewer tweeted: "I was not expecting Cal to die... I was literally denying it, thinking they wouldn't kill a main character until I heard the bleep."
:: Casualty returns to BBC One on May 6 at 8.05pm.
