I know, right. Characters on TV shows rarely seem to seek out information on the stuff they're stuck in the middle of. It's something that struck me about this show, but also about Once Upon a Time. If I were in one of these shows I'd head to the library and check out every book on either ritual magic or fairy tales respectively.
At the very least I'd of memorized any book of shadows I had cover to cover. It really seems like none of them really have. I guess perhaps Faye and Melissa and Nick might have an excuse because they might not of gotten a lot of time with it, but Diana and Adam..
A woman can move a lot faster with her skirt up than a man can with his pants down.
