Raven is attacked again (in Dark Desire) while she carries the baby, and Gregori gives blood to the fetus, even communicates with it, further sealing the bond between him and the child.
In case he turns vampire, he appeals to Aidan not to hunt him alone, but to get his brother Julian to join him.
After Gregori said this he told Aidan that he would “go to ground” (When a Carpathian shuts down heart and lungs in order to sleep in soil).
The five-year period has passed; Gregori has come to San Francisco, where Savannah has ended her tour to claim her.
Knowing that she's in shock and grief because of her friend, he takes her to his property to heal, intending to complete the mating ritual the next day.
