While some have obvious symptoms, others initially baffle the medical team. Consultants Graham and Firas are running A&E and tensions run high as police suspect a patient has come to King's with a concealed weapon. 'I guess it's part of King's - you expect the unexpected,' says Firas. Mother-of-four Hillary, who's 58, arrives in Resus by air ambulance with a severe head injury after falling from her horse. Hillary stopped breathing at the scene of the accident, blew a pupil and was put into an induced coma. Firas suspects a life-threatening brain injury and Hillary is put in the specialist neurological unit while two of her children rush to King's to be by her side. Meanwhile, Icylyn comes to King's with a bloated abdomen. Consultant Graham initially thinks she might be pregnant, but tests rule that out and her symptoms throw the medics. Icylyn will have to wait overnight for diagnosis, but Graham is concerned that her symptoms could be the result of something serious. Icylyn is accompanied by her best friend Tony, who talks about their relationship and ponders what's really important in life. And 14-year-old Chloe is in Resus after getting involved in a fight after school. Doctors are worried that she may have injured her neck. As she's treated, Chloe talks about her love of high street fashion, the importance of having her nails painted regularly and what the people in her life mean to her.
