Melva's trance was broken at the moment Vance came to stand between her and Mervin, blocking him from her view. She could finally relax as her control over herself was returned to her. It was very close. A huge wave of relief washed over her after thinking that she would not need to resort to biting her own tongue to stop her from talking.
"Shut up, Mervin!" growled Vance, his hands reaching for her who was standing behind him as though making sure she was safe and well hidden from Mervin. "How dare you speak to her!"
Although Melva was unable to see Vance's face because she was staring at his back, she could tell that he was livid from the way he snarled at Mervin. His hands that were keeping her in place, safe behind his back, showed how possessive he was. But she would not complain about that for now, because Vance had just saved her from having to blabber everything she knew to an outsider and lose her voice for good. This time, she was actually grateful to him.
