S1, E5: Diana hovers between life and death, between Georg and Ben. At the last second, she gets revived because the doctors, through Erika Green, know what they are dealing with: Levofentanyl. The chondroitinase ABC administered by Edmunda secretly contributed to her recovery. Diana seems to feel more again, and her pain indicates a change in her body. Even though Georg, who has arrived in England, finds it hard to leave his wife alone, he goes to the EAD and confronts his former colleague Bryan Patel. He finds out what drove the young Rovers players to death and disease ten years ago: an enzyme that interferes with the genetic material. Chai Dan is determined to find out who is behind the attempt on his life. Anne Hsu subjects Fritz, the clinic's majordomo, to Ling Chi - the art of performing as many cuts and amputations as possible without the victim dying to find out on whose behalf he switched her uncle's pills. Detective Erika Green meets a man, Paul. The two hit it off right away. A glimmer of hope emerges alongside the everyday life of the investigation and the constant fear for her drug-addicted daughter Ava. Edmunda is at the finish line. She and Clara Fischer can finally inject themselves with the first two doses of the new enzyme. When Andreas Müller shows up at Diana's bedside, something major comes to light: there's something that connects the two. Georg gratefully accepts that Andreas is here to take Diana to the clinic in Austria for safety. During the flight, Georg tries to question Andreas about Henri's collapse. But his old friend refuses to answer straightly, reiterating that one has to accept sacrifices. Back in Austria, Georg starts looking for Henri Tadjou and goes to Vienna. There, Georg learns that the terminally ill Henri is supposedly in perfect health and was acquired by a new club.
