Have a taste
Bella was in her house close to the castle reading a book to her own comfort, she had used that time give herself some personal space and focus on finishing her book while Coast was still working.
She was feeling thirsty so she went to the kitchen to make a cup of tea and returned back to reading in the sitting room.
She took a sip of her tea and realized the tea wasn’t that good and it needed more sugar so she went back to the kitchen to get more sugar.
Almano who had just finished his shift heard that Bella was not in the castle but in her house, he went to have a word with her when he saw her leave her cup of tea into the kitchen. With the bottle he had gotten from his friend still in his pocket, he snuck in and put a few drops in the tea then snuck out.
Bella came back and didn’t notice a thing because Almano had masked his scent so well, she mixed her tea after putting the sugar and drank it.
