He watched her from his room.
On his laptop, like the way a lion watches its prey carefully before diving for the hunt, but this wasn't any normal hunt where one would be patient, since time was not what Giovanni had.
He knew that it wouldn't be long before his grandfather storms his way, over here in his villa to demand the identity of the woman, who's carrying the next generation of the Russo family.
He has no idea what his plan would be, but one thing is clear, he wouldn't allow anyone from his family try to determine Marissa's next step for him, he's the one who got her pregnant and he would fend for her until he knows what exactly to do with her.
So, that's why she's here with him, but in an entirely different room where he's going to instill inside her that her life is not hers anymore. Everything changed the moment her body consumed his seed, and made her egg fertilized to have his pulp.
