"I think I get what you mean. You knew you had power, that you had the stuff, but you didn't know how it all worked. I was like that when I first stumbled into my first spell, got really excited and then didn't know how to get to my second. It was pretty embarrassing, actually. I was really afraid that it was a fluke, that I wouldn't get to learn another spell."

But she'd gotten there, even if it was the hard way and had risked some people she cared about by mistake. She fixed it, at least!

"No, I don't think so. First thing you should probably do is figure out what blood you have though, and then you can figure it out from there. That way you can know what to expect if your blood powers manifest by accident. One day I was trying to sleep and I stumbled into astral projection! But once I figured out what was happening, I stop worrying about it happening by accident and started concentrating on making it happen by my own wishes."

Which she wasn't successful at yet, but she was making progress!
