10. Dawn of the Ed (Series 24)
The explosive opening two-parter of Series 24 kicks off with a massive fire at an abandoned mall, pushing the ED team to their limits. The stakes were high, and we were gripped from start to finish. But it wasn’t just the incredible stunt work or the harrowing rescue scenes that made this episode stand out—it was the devastating death of Junior Doctor Heather. Her sudden, tragic end in a burning elevator still sticks with us.

9. Duty of Care (Series 26, Episode 17)
The first episode set in Cardiff was one to remember. A motorway pileup leading to a gas leak and explosion provided intense action, but the real heart of the episode came from the fantastic character development, particularly with new Registrar Tom Kent. The visual shots of the gas cloud and the team working under pressure gave the episode a tense atmosphere that kept us on the edge of our seats.

8. A Child’s Heart (Series 30, Two-parter)
Following a tragic boat explosion in the Series 29 finale, A Child’s Heart follows the emotional aftermath with Charlie at the forefront. As one of the last remaining original characters, Charlie’s health scare and collapse from a heart attack made viewers question whether they’d lose him forever. The uncertainty around his fate in the second part of this episode was heartbreaking, but it kept us invested in Charlie’s journey.

7. Before or Fall (Series 22, Episode 24)
This episode is a raw and powerful depiction of mental health struggles. Ruth Winters, a junior doctor, is found attempting suicide after months of struggling with her mental health. The shocking moment when she is discovered in her bedroom and brought into the ED was devastating. The emotional aftermath, especially the scene where clinical lead Harry Harper addresses the system’s failure to support Ruth, made this episode a turning point in how mental health issues are addressed on the show.

6. Born Lucky (Series 29, Episode 5)
This intense episode revolves around a horrific minibus crash, and the shocking death of Jeff Collier, one of the show’s most beloved characters. The moment where Jeff sacrifices himself to save everyone else, only to meet his tragic end, had us all tearing up. The emotional scene where Tamsin desperately searches for Jeff after the crash is one of the most heart-wrenching moments in Casualty history.
