Plot hole: People are always told to not use their mobiles while in the hospital. However, the staff constantly use theirs.
There's No Place Like Home - S28-E16
Character mistake: The old photo of Sylvia and her friend shows them in RAF uniform. Sam, who is a serving British Army officer and could be expected to recognise the very obvious differences between the uniforms, keeps referring to Sylvia being in the Army and Sylvia does not disagree with her.
Visible crew/equipment: In the episode on Sat. 21st July 2007: At the end of the episode, Guppy is seen by an ambulance, and in the window you can see all the camera equipment.
Plot hole: Would Holby Control really send two technicians on a shout together? Surely they should have at least one proper paramedic who can perform the activities needed? Also, how come in earlier episodes when Nikki hasn't passed the Technician exam, she still has Technician on her badge, and not trainee or something?
Character mistake: Charlie says that Iain has been a paramedic for ten years. Iain actually joined as a student paramedic in August 2013 immediately after leaving the Army (in which he was an infantryman, not a medic). As 'Casualty' operates in real time and this episode was shown in February 2019, Iain has therefore been a paramedic for only five and a half years.
Continuity mistake: Louis Fairhead's year of birth is given as 1992. He was actually born during Series 11 in 1996.
Revealing mistake: When Alicia slaps Bea, her hand actually misses Bea's face.
