Bonnie had arrived at Xander's camp a few days before, after making the decision to skip visiting Caroline like she had originally planned. But she had planned to leave some of her supplies at Caroline's and Damon's place during her original detour because she wasn't going to lug all the new supplies she had gotten from Danny through the hotzones on the way to Xander's. But because she couldn't think about Caroline without flinching, seeing her was out of the question.
So Bonnie had ditched her supplies in an abandoned cellar on the way to Xander's, with the intention of picking it up later. It was why she was coming back to the camp so late that night. She had run into a few Croats while retrieving her supplies, but she was fine and without a scratch on her.
The camp was quickly coming up in her view, when her eyes caught something falling from the sky. She stopped and narrowed her eyes, when she realized, no, it wasn't something falling from the sky. It was someone landing. For a moment, she considered her options, before she decided that she hadn't heard of a flying Croat before and she doubted that was the case now.
So she quickly left her bags full of supplies where she had been standing and approached the figure. She already had a spell ready in case this went in the wrong direction, but Bonnie hoped she wouldn't have to use it. "Hey, you," she called out, as she slowed her approach. Bonnie was just far enough away that she could run if she needed to, but still within talking distance.
