The series continues with a touching episode dedicated to love. Concerned young parents Nicole and Stefian arrive in Resus by ambulance with their 19-month-old baby daughter Xah'Nae. She's been vomiting, has a high fever and has become floppy and unresponsive. The King's medical team are concerned that Xah'Nae may have a life-threatening infection around her brain and in her spine, possibly encephalitis. Doctors hope a strong mixture of antibiotic and anti-viral drugs will stabilise her. Meanwhile, 61-year-old Christine is brought into Resus, unconscious after collapsing in her sister's bathroom. She had a stroke 10 years ago, and the doctors are concerned that she may have had another. As the medical team treats Christine and tries to establish why she passed out, her husband Dave contemplates their life together. They've been married for 42 years, and Dave paints a picture of a relationship that's tempestuous but founded on true love. Graham, who's 52, has fallen over in the bathroom and hit his head. He's been brought in to A&E by his adoring sisters Christine and Jean, who are also his carers. Graham has Down's syndrome and has recently developed dementia. Christine and Jean stay by Graham's side, giving him constant reassurance as he's scanned and has his wound treated. The two sisters discuss their love for their little brother and the challenges and joys of caring for him, and contemplate what the future holds for them all.
