Meg was browsing through the pages of Daphne’s book, hoping to find something that could prove Cas’ innocence. While she read she listened carefully to hear if Zoey was on her back yet.
Maybe everyone was awake again. After all, the building was full of staff. Meg wasn’t in prison, she was being held custody, until someone told her how long she’d be convicted.
So it was very assumable Zoey had been caught and thrown out. of maybe she’s been arrested for trying to help Meg escape.
“Hello?!” Meg shouted to be sure.
“Is anyone there?” Meg yelled.
Again no answer.
“Zoey!” Meg yelled again.
“Okay, stay calm” Meg told herself. “Zoey’s just very confused and upset about the trial. She can only think about Alexia, so she forgot about me”
The other theory was that Zoey got killed, because she tried to help Cas.
