Cassandra is… curious, when she sees Dean set up shop. It doesn’t look like anything she’s seen before (she’s spent the past 5+ years trapped in her childhood home with her family’s murderers, and before that she didn’t really leave Whitestone; she was too young. So she hasn’t exactly gotten out much), and she cannot help but drift closer when she’s no longer behind the bar.

“What is this that you’re doing?” Her curiosity is evident in her voice, in the tilt of her head and how she’s studying the equipment thoughtfully. She's making no effort to hide it.
