Olivia planned to return home to her family, since there isn't any scene for her for two days.
They will be shooting for the side characters and it's up to her if she wanted to be there.
The answer is obvious. Why would she be interested?
She had missed them within the few days that they didn't get to see each other. She had gotten so attached that phone call alone isn't helping her missing feelings.
It was as if it had been years that they last met each other.
She suddenly felt excited, while Brian was fooling himself that perhaps he was the reason why she was looking like that.
She had a 5 minute shoot before leaving, which was just the scene of when Elizabeth got home after work.
She was seen crying so hard in her room. She looked so miserable and wonder why such happened when she finally felt so confident and happy.
She now believed that he only wanted her body, but she was done.
