Throughout Dear Child
In the middle of the night, Gerd learned that a woman resembling Lena was in a hit-and-run incident. He called Matthias and Karin and arranged to meet them at the hospital in Aachen.

At the hospital, Matthias and Karin did not believe the woman to be Lena. However, they immediately broke down upon seeing Lena's daughter, Hannah, as she looked exactly like a young Lena.

Police later uncovered that the woman was actually Jasmin Grass, who was kidnapped by the same man who kidnapped Lena Beck. Jasmin was forced to assume the identity of Lena, and raise Lena's children, Hannah and Jonathan, as her own.

DNA testing revealed that Hannah and Jonathan were half-siblings. Hannah was fathered by Lena's ex-boyfriend Florian, while Jonathan was fathered by Lena's captor.

When Matthias learned of the DNA testing, he was furious. Matthias and Karin had been arranging for Hannah and Jonathan to live with them, since they were the children's closest known relatives. The revelation of Hannah's biological father would prevent Matthias and Karin from being their legal guardian. However, Gerd was more concerned with solving the case and believed that Matthias and Karin were rushing to become Hannah and Jonathan's legal guardians too soon.
