After Nicole's phone call with Dan, she decided to freshen up and then go to the Princess' room to ask her if she could speak with her brother or if he had called and had given her the go-ahead to give her his number.
After she had freshened up and changed into her pyjamas, she picked up her phone and was about to go out of her room when she saw a missed call from an unknown number. She decided to call the number back to know who it was before heading for the Princess's bedroom.
Back in Ben's room, he had wanted to text Nicole, but after giving it some thought, he had decided against it. Since it was his first time talking to her as Ben, he'd rather do it with a direct phone call. He wanted her to hear what his voice really sounded like.
