The Man Smiles that she had recognized him, "We're going do a small ritual where you'll belong to me forever, you better be prepared." When he said, Marina got scared a bit, as she knows what ritual he was talking about, as that ritual was in the game. As it would make Woman bound to the man they had sex with. The Ritual would require the woman's virgin blood, and the Male's Blood. If the Woman was no longer a Virgin, and wasn't claimed, she vulnerable to being claimed, even Widows, they can be easily claimed, and by how? There is another ritual that would temporarily make the woman a Virgin and the Male could use that time to get her Temporary Virgin Blood to claim her as his.
