Rosa was fighting to maintain control over herself from head to toe now more than ever. She knew she couldn't act like she knew Silver—not when it could spell doom for them both. The connection between them had to remain hidden from Zarek and single slip could be the difference between life and death for him in this weak state of his. She was painfully aware of it.
Hang in there, and you do dare wake up now.
In a twisted way, she was glad that Silver was unconscious. The thought of him seeing her half-naked and pinned to the ground by Zarek's oppressive weight was too much to bear. But worse than that would be the possibility of being violated in front of her lifetime protector, the man she knew loved her deeply from afar all this time. The shame of witnessing her being humiliated like that would be worse than death for both of them.
