Connie's old boss Andrea returns to the ED as the specialist doctor to a young heart patient, and her insistence that the boy should be operated on, despite his obvious weakness, makes Connie suspicious of her motives. A young man sneaks into the department, deeply distressed by a huge abscess in his mouth, and Lofty becomes concerned for his mental health. Dixie's nose is put out of joint by Tamzin and Jeff's relationship, claiming she doesn't trust Tamzin - but is it just jealousy? Ash visits Rita at home and ends up covering for her at work, while Charlie gets a day off - which he spends hanging around the ED.
