Deliberate or unintentional, It is after all a Sabotage
One of the men who were the supposed father of Rebecca used to work As a doctor at the Christ Hospital. This find was not only disturbing but also disgusting and cringy. No one in his right frame of mind can possibly forgive the fertility doctors, and neither could Rebecca’s family.
Still, they didn’t know whether it was an unintentional mistake or deliberate sabotage. If the person that worked in the Christ hospital as a doctor was Rebecca’s biological father, then it is apparent that it would have been intentional sabotage. But if not, then it was still an unforgivable mistake and goes against ethics.
