"Whoa, whoa. Slow down, I got as far as, 'the full moon's tonight, uh oh' and you lost me." Henry stated after Dean had begun to explain the case to them.
"Alright." Dean sighed, getting ready to explain it again.
"Dad said in his journal that one time, exactly 100 years ago, a pack of werewolves joined together to feast and strengthen their blood line. That happened on the night of the full moon. Granted, there's a full moon every month, but that's beside the point. According to dad, the stars aligned in a pattern representing a pentagram when it happened 100 years ago. This gives power to the werewolves and therefore makes them more likely to attack, and they do it in groups. I didn't want to say why we were coming this way because I didn't want to freak you guys out, but the fact of the matter is that the stars have re-aligned again. And, bingo, here we are 100 years later with the same situation." Dean finished and took a long breath, looking at an astounded Henry.
Sam was used to the weirdness in their lives and Dean could tell he was pondering the information. Dean waited for it to register in his brain and for a full-blown plan to leave his lips. "The question is, where are they going to be and when. Also, how are we going to stop them?" Sam asked.
"Whoa, one question at a time there Sparky. I don't know about the how quite yet, but I do know the where. Since the pentagram alignment in the stars gives them power, I figure being directly under it would give them the most strength. That would be why we're here; we just have to find the exact hot spot we're looking for. So, now it's you turn. You finish figuring out the where and when; I'll do the how." Dean said, looking at Sam.
Sam got up and went to his laptop and Dean to the journal. Henry sat there dumbfounded and started to wonder if he would ever get used to living with the Winchester brothers.
Alalalalala
"Okay, according to this constellation map, the pentagram alignment dad talked about is directly above Illinois." Sam sad unbelievingly.
"You're freakin' kidding me right? Illinois that's just our luck." Dean said with a huff and a role of his eyes.
"Why? What's wrong with Illinois?" Henry asked, clueless as to what Sam and Dean had been through.
"We, uh, got into some trouble with a shape shifter in Illinois and, well, Dean got accused of some things he didn't do." Sam explained, recalling the close calls they had with the police.
"Like what?" Henry asked, more worried than curious.
"Like murder" Dean replied.
"Oh." Henry said, biting his bottom lip uncomfortably. "That's not good."
"No, it's not, but it's part of the job." Dean said.
"So, I know the where, and the when's tonight. Did you figure out the how?" Sam asked hopefully.
"More or less. I mean, we know these things die with a silver bullet to the heart. The only problem is, there could be dozens of these things and we don't specialize in numbers. Just complex crap." Dean replied.
"Okay, well werewolves don't change until the moon comes out so, that gives us five hours to get there and come up with a plan." Sam said. "I'll go grab our stuff." Henry said, going into the bedroom.
"Hey, Sam?" Dean asked.
"Ya?"
"I'm starting to wonder if this is a full moon or a blue moon." Dean pondered.
"Why is that?"
"What are the chances this would go down in Illinois?"
