When Sam saw that the call was from Celeste, his mind went blank for a moment.
Celeste rarely called him because, as Angel's mother, she could learn about many things through Angel.
Most of the time, when Sam and Angel went somewhere, Elowen would drive them, and Celeste could find out what they talked about and where they went from Elowen.
So, this call seemed highly suspicious.
Sam tried to pretend he was asleep. After all, it was late, and it was normal not to see a call if the phone was on silent.
He thought he could reply with a text tomorrow morning, pretending he hadn't seen it, and maybe she wouldn't want to discuss it anymore.
Sam had a bad feeling. A call at this hour was definitely not good news, likely related to something that had happened recently.
The phone rang for a while before finally stopping.
