From the seventh episode of the second season Regina Christmann is replaced by Andrea Schäfer. She is then the secretary of boss Engelhardt. This computer-expert helps the Cobra 11 men with their investigations. Beceause she knows her colleagues very well, she often can think of their requests before they have asked her. Sometimes she wants to be something more that just a secretary, wants action and by this she gets sometimes too many self-confidence. Also Andrea is in her love-life involved with Semir. She and Semir have a sort of on-off relation, which gets steady at the start of the sixth season. At the start of the 8th season both marry eachother. This marriage leads to a baby: in the beginning of the 10th season their daughter Aida is born. Because she wants to use all her time to raise their daughter Andrea decides to quit her job at Cobra 11. But this doesn't mean she doesn't appear in the serie anymore: often the privat-life of the family Gerkhan plays a role in the serie. The character of Andrea is still impersonated by Carina Wiese
