Since Charlotte had decided to get rid of Eduardo, she made a move quickly. Her plan was simple, separate the two of them using one means or the other.
She faked an accident with the car taking Eduardo to school. By the time he opened his eyes, he found himself in the Rossi's mansion. He had been brainwashed into believing all his family was dead and they had adopted him... No, they bought him as a slave.
Charlotte gave the Rossis permission to do whatever they wanted with him, so they went ahead and made him their youngest servant.
