Just then Draco walked in. When Hermione had decided to pay Draco an impromptu visit, she had not considered Narcissa Malfoy to intercept her. However since Draco was living with his mother and his aunt, she could hardly just walk in and announce that she wasn’t there to talk business. So she fidgeted and waited for Draco to show up. Thank god he showed up. She couldn’t talk about Dobby if her life depended on it at that moment.
