It was the first time that Shein neglected Riley's whereabout due to his anger at her. He didn't check where she went to and he didn't call her either.
He was confident that Riley will be safe without him worrying about her. He knew that Riley was tough. Now, he was finally worried because she wasn't home yet and it was almost midnight. She was even at the police station which was really odd.
He was debating between going out to fetch her or to wait for her at home. After few minutes, he picked up his coat and went out. Just as he was entering his car, the tracking on Riley's phone moved and was on her way back home.
Shein went inside and decided to wait for her instead of going out or going to sleep. He turned off the lights in the living room and sat on the couch while waiting for her.
