Lydia didn't like not knowing things. It really bugged her. She was a very smart girl, but she was clueless as to what was happening to her. Even Cas didn't seem to know for sure and he was an angel. Lydia worried about what it could be. Could she be a danger to all of these people? She didn't want that, but she knew it was very possible. Peter Hale had used her to bring him back from the dead. Maybe he knew what she was. But Peter Hale wasn't here, so Lydia couldn't even ask him even if she wanted to. And she probably wanted to stay far, far away from him.
She looked at Cas, and then Sam for a moment before shaking her head. "No, but I came really close at the winter formal I think." She'd been hurt badly enough to be in the hospital. But then she'd disappeared and she still didn't know what had happened during those days. Maybe if she did know what had happened to her then, she'd know what was happening to her now.
Lydia was glad she was going to go to the doctor with Sam. She hoped they'd be able to at least help him with the pain, even if they couldn't pinpoint what was causing it all. It definitely wasn't anything natural that was causing it, so it might not have been able to be determined by a doctor. Hopefully Cas could help with that part of it all. "I'll take notes or something, if you want." She offered, wanting to make sure that Cas got an accurate interpretation of everything the doctor would tell Sam.
