It has been exactly three months since Brina lost her consciousness and even though her age has returned, she hasn't awoken yet.
During those months, Luc never left her. He literally moved into the Villan's house. And though at first, Rowan doesn't like the sound of Luc living with them and staying in the same room and even in the same bed as his daughter, he knows that Luc's presence might help Brina.
Luc also showed him how much he loved his daughter.
Rowan and Lorcan had also stopped going back and forth at Astraea because they knew that it was futile. Verena just assured them that if ever they find a way to help Brina wake up, they will eventually send one of Gavril's men to deliver the message.
Bell and Brylee along with their husbands also stopped sneaking into the facility of Project Regnum at night when Xander was almost caught once. He went there when Bell was at Villan's house without her knowing and he almost got caught.
