Samantha is nothing if not expressive and her face now is showing disbelief as she turns back to Sylvia, ignoring Nancy. "Wow. Why are you talking to her? Back in Manchester we know how to deal with traitors." She turns her gaze back on Nancy, just to make sure she hears every word. "We shun them. They're no longer considered a witch at all."

As for Sylvia, she remains impassive. She'll let Samantha play her hand before she reveals hers. See how far that gets her.
