They were stumped. The boys couldn’t find out anything that could help them kill off this thing, and who knows how many people are sending those e-mails right now. The only thing they could do was call Bobby. He picked up on the first ring.
“Hey Bobby, its Dean” Dean barked down the phone, a little too harshly. But his patience was wearing thin, there had to be something they could do.
“I wondered when 你 guys were going to call, what do ya need” Bobby replied.
“Well, it turns out it’s the smith sisters”
“The Smith sisters? But that’s just a legend...”
“I know bobby, we went through this, its defiantly them. Anyway it turns out there sending those chain 电子邮箱 things, and we have no idea how to stop them”
“Chain e-mails, huh? Those damn things get on my nerves....”
“Okay...Do 你 know how to stop them?”
“Sorry, I’ll call ya if i get anything”
Bobby hung up before dean could reply, he sighed.

Dean collapsed on the motel bed, exhausted from the long night. They'd spent all last night digging up everything they could think of, but nothing fit, dean knew there was something he’d missed, he just didn’t know what. Dean pulled out his dad’s journal, they’d been through it over and over, but he decided to look again. He studied each page carefully so he wouldn’t miss anything. But he still couldn’t concentrate. So he flicked through them, barely catching the title. Wendigo, Skinwalker, Vampire, Loki, Djinn, Tulpa, Banshee... Dean froze, why hadn’t he thought of it before, it was obvious. He flicked back through the pages until he found it again, Tulpa.

“I’ve got it” He 说 almost too excitedly, whist he shot up and made his way over to Sam. Dean almost shoved the book in his brother’s face, and watched to see his reaction.
“Okay, it’s a possibility” Sam made a ‘facial shrug’ and handed the journal back to dean.
“A possibility?” Dean shouted,
“This is it, everything adds up: the chain e-mail, the Tibetan spirit sigils, the...”
“Tibetan spirit sigils? What are 你 on about?”
“I saw them, on the e-mail, but i just shrugged it off. That’s what I’d forgotten, it was right in front of me.” “Your sure 你 saw one?”
“I’m sure...ish”
“Thats not sure”
“It’s sure, just with an ish, which is good enough for me”
Sam sighed, grabbed his 夹克 and headed for the door.

“Where the hell are 你 going?
“To the scene, we can’t just jump i there if your only sure-ish”
Sam left, closely followed 由 his annoyed but smug brother
