Isis vs. Nephthys and Osiris

Case Description: Isis alleges that her sister, Nephthys, dressed up in Isis' pajamas and pretended to be her in order to get into Osiris' bedroom.

Case Status: Guilty as charged. Not only did Nephthys trick Osiris, she gave birth to his son, Anubis. Isis didn't hold it against the jackal-boy, though, as Isis adopted him as one of her own children after Seth ordered Nephthys to leave Anubis to die in the desert.
