When you watch Supernatural Season 13 Episode 11 online you'll see just how far someone will go to provide body parts to monsters. When Donna's niece, Wendy, goes missing she calls upon Sam and Dean to help. Sam is, at first, reluctant to help because the FBI has gotten involved, but Dean reminds him Donna is family. Sam, Donna and an FBI agent named Clay go to the police station to interview a suspect, but it goes bust when they realize he doesn't know anything. Thankfully, Dean is able to track down a lead which brings them to a diner called Conner's where a long list of missing people have been before they were taken. The manager at the diner admits he hands over people he suspects won't be missed, and the guys are shown a website which sells off human body parts to monsters. The guys are able to track down where the feed is coming from thanks to Clay, who meets them at the warehouse. They soon find out Clay isn't working for the FBI, but is actually the one behind the website. Clay is able to take Sam hostage and starts selling him on the web. Want to see what happens next?
