will guest-star as her Holby City character Donna Jackson in the opening episode, as part of Kent's plan to have characters from the two shows cross-over several times a year. While Jacobs has appeared in several Casualty@Holby City episodes, she had never before appeared in Casualty itself, and deemed the two shows very different, to the extent that it felt like "doing a completely different job". In terms of her character's development, Jacobs stated that "Donna really has to put herself on the line in this episode and its not something she's used to doing", explaining that now she has her orphaned niece to care for her priorities have changed: "She's had to accept some responsibility and it's not now just about which man she's going to sleep with next". Guy Henry guest-starred as his Holby City character Henrik Hanssen in episode 24. The character had only recently joined the Holby City cast as the hospital's chief executive officer. Hasina Haque joined the Casualty cast as new staff nurse, Madiha "Mads" Durrani in episode 1. Mads' storylines included: an attraction to Lenny Lyons and being raped by her taxi driver. She left in the episode 47, the series' finale. Cheryl Campbell joined the cast for ten episodes as the new joint clinical lead, Miriam Turner, in episode 25. Miriam fought against Nick for the sole clinical lead position, which she won. However, she then decided to return the position to Nick and left the show in episode 35. New trust doctor, Dylan Keogh arrived in episode 28 to replace Ruth following her sectioning in episode 21. Ruth returned to the ED as a doctor in episode 45, but Dylan continued to appear. Former Waterloo Road star, Christine Tremarco who guest-starred in the previous series as Jessica Harrison's friend, Linda Andrews returned to the show in episode 38 as the new clinical nurse manager, replacing Tess Bateman, who returned to her former position as ward sister. However, in the series finale, Linda chooses to resign from clinical nurse manager and accept a staff nurse position with Tess taking the role back from Linda. The series also saw a number of departures. Junior doctor, Yuki Reid, left the show in episode 16 after taking the blame for Lenny and deciding to take a research position in Birmingham. Sophia Di Martino, who plays ambulance technician, Polly Emmerson left the series in January 2011, with Polly's exit scenes airing in episode 34. Polly, who was to leave the following day for a new career path, decided to fix things between Dylan and an unhinged patient. Unfortunately, the patient is armed with scissors and is stabbed. In a tense episode, Polly bleeds to death, leaving the department devastated and Dylan feeling guilty. Lucy Gaskell, who plays Kirsty Clements, became pregnant, but rather than take maternity leave, decided to leave the show. Kirsty's exit aired in episode 46 when a patient encourages her to make a decision about her future and she chooses to leave Holby with daughter, Nita and live in Wales. In the series finale, Adam Trueman left after a tough few weeks, marking the end of his four-year stint on the show.
For Series 25, Oliver Kent continued in his ongoing role as the show's Series Producer with Belinda Campbell continuing as the show's Executive Producer until Episode 45. Johnathan Young, former Executive Producer of The Bill, took over as Executive Producer from the final two episodes of the show. Mark Catley, the show's writer, continued as the show's Consultant Producer. For this series, the storylines were written by four of the show's writers: Ellen Taylor wrote the storylines for episodes 1-11; Paul Logue, Sasha Hails & Hamish Wright. There was no Story Producer credited for this series.

Critical response
The series premiere was selected as recommended viewing by What's on TV, who deemed the episode "compelling". Jane Rackham of the Radio Times praised the episode, advising viewers not to be deterred by the "choppy editing" and hand-held camerawork, commenting that it ultimately "meshes together rather well." Rackham's only complaint was the unprofessional behaviour exhibited by Lenny, which she felt "beggar belief at times". The critical response to many episodes on the holby.tv forums has been extremely critical, with many viewers complaining that Casualty is too storyline-based and that there is very little realism or medical procedure discussed in the show anymore.
