The latest instalment saw Adam's consultant, Mr Lockhart, throw him under the bus after deciding not to take the blame for his mistake amid Erika's complaint. Adam digs himself an even bigger hole after his attempt to convince Erika to withdraw the complaint backfires and her sister berates him.
Things take a dramatic turn, however, when Adam is forced to assist an emergency birth on the floor of A&E and ends up saving an expectant mother's life. When Erika's sister sees the incident play out, she agrees to drop the complaint. Meanwhile, Shruti questions whether she's cut out for the job.
