Olivia made the decision to move out of the house Joseph got for the both of them, because there was no point in her staying there anymore.
She had called her mom earlier to come pick her up later in the day, when she must have been done with packing and cleaning.
When she was done with cleaning up the living room, she moved to the bedrooms. First, she went into the room Jordan had been staying, to make sure it wasn't messy when he gets back.
While cleaning the room, she saw some clothes littered on the bed and decided to fold them and place them back in the drawer when she found some envelopes in the drawer, with her name and address on some of them. She became curious and decided to open one of the letters.
Olivia received the shock of her life. The letter had been sent to her by Joseph after the time of his supposed death. She was confused and wondered how the letters ended up with Jordan.
