Wicked plan gone wrong

"This is a blood wine I ordered from Rosenheim. It's called Crimson Dew. It is very rare, and I only got a bottle of it," Criselle said, holding her own glass of wine. She noticed Theron wasn't given a glass. "My apologies, Mr. Kline. As I have mentioned, I only got a bottle, and it seems not enough for all of us. Clark," she called the butler. "Get a wine from the cellar."

"That is unnecessary," said Harold. "You should have mine, Theron. I have tasted this wine back in the royal capital, and the wine seems too strong for me."

Standing among the line of maids in the corner, Sienna's eyes fell on the glass Harold was giving to Theron where she could sense a witch's magic mixed with the wine. 

Why does the wine have a witch's magic? A crease of worry appeared on Sienna's forehead. She looked at Criselle, and her eyes narrowed. She couldn't fully see the vampiress's expression from where she was, but she could see her staring at the glass Harold was holding.
