This episode shows when Alexis was seeing Roger Grimes and she mentions that Blake has thrown her out. In earlier seasons, she claims that she was pregnant with daughter Amanda when Blake told her to leave. If she and Blake hadn't been having sex where did Amanda come from then? Could she have been Roger's daughter? Or maybe Alexis was telling the truth about the swiss ski instructor being Amanda's father. Maybe Alexis figured that another way of getting revenge upon Blake was letting him think that Amanda was his child and then she would get some of the Carrington fortune.
