While she didn't like being stuck in this world, she had her sister here. And living with her, just the two of them, working on their powers, being sisters. Like real sisters. They'd recently gone and got their very own family spell book to start building, and then Billie had dragged Christy shopping. Of only for a while. She'd also taken her camera, which was now filled with dozens of pictures of the two of them looking totally normally. She also wanted to show Wyatt that, and Paige. Christy was doing good, and Billie had complete faith in her.
Bag, book and camera in hand, Billie had left the house. It was a bit of a hike to the complex, but she felt like taking the walk. She wasn't too worried, she had her anti-charm thing on, and Billie was more than sure she could keep a vampire at bay. As for the hell god, again, she could get herself out of there if she needed to. She couldn't just not go on with her life.
The streets were pretty quiet as she glanced one way, and then another, before half jogging across the street. While she was at the complex maybe she could help Paige with some research. Apparently there was a lot of that going on. She knew her sister didn't like the Charmed ones, but Billie didn't want to break off contact with them. Wyatt, Paige, Phoebe, they were all important to her, and she wanted to keep those connections.
