Davina was wondering around aimlessly in Hogsmeade, as per usual. She didn't like to shop that much, unlike most girls, so she just walked around, doing a bit of window shopping then eventually going back to school. Sometimes she stopped for a drink, as well.
Davina saw The Three Broomsticks come into view. This would be one of the times she stopped for a drink, she decided. She walked across the street and stepped through the door and into the building.
Davina saw Catalina and Mariana at a table together, and near them was a Slytherin girl she hadn't met before. She wanted to go and sit with the girls she knew, but there wasn't another chair at the table. She could go and sit with the Slytherin girl, but she wasn't sure if she wanted to. She didn't have the best impression of Slytherins, thanks to Black.
Davina walked up to the bar and ordered a drink, to prolong her decision. She sat at a stool while she waited for the woman, who she couldn't remember the name of, to get her a butterbeer. After what seemed like a second, she had her drink. Now what?
