Something was nagging Stiles as he walked into Derek's library for his lesson with Deaton. Lydia had been acting strange the past few weeks and what she had said after the divination made Stiles concerned.
Just because he wasn't pining after her anymore didn't mean that Stiles was going to stop paying attention to her.
"So Deaton, you know things right?" Stiles asked the man.
"That's a vague way of putting it, yes." Deaton answered.
"So what does it mean when a person's aura changes?" Stiles inquired.
"Usually a change in someone's aura has to do with a change in themselves. Subtle changes reflect minor things, however drastic changes can be something like a great tragedy or in the case of lycanthropy being bitten by an alpha." Deaton explained. "What's brought on this query?"
"Well Lydia's aura changed a few weeks ago, but it's not quite the same way as with being bitten by an alpha. Wolf aura's have tones of red and in Scott's case when he was turned a deep blue. Her aura kind of went dark and for the most part is black, when before it was always light and at times pink." Stiles answered.
"Then there's what happened at the divination the other day." Stiles added. Deaton was quiet but his expression encouraging, waiting for the teen to continue.
"She identified the building where it's supposed to take place. It's not in the normal areas of town Lydia hangs out in. Not unless she has a bat cave in one full of shoes and chalkboards filled with math equations." Stiles concluded.
Deaton was quiet, his expression thoughtful. He then grabbed a book from one of Derek's shelves and flipped a few pages. When he stopped flipping he read for a few moments before snapping the book shut.
"Banshee." Deaton said with finality.
"Ok I'll bite, what's a Banshee?" Stiles asked.
