Bobby's Numbers

When Bobby is captured by the Leviathans and taken to Dick Roman's office, he gets a chance to examine the files in Roman's briefcase which relate to the Leviathan's grand plan. There appear to be a number of schematics, and maps relating to the location of infrastructure such as dams and power plants. As he examines a map, with red markers in Wisconsin and Ohio, he seems to have an epiphany as to what the Leviathans intend to do.

As Bobby is escaping from the Leviathans, he is shot in the head by Dick as he gets in the van with Sam and Dean. As he lapses into a coma, Bobby's subconscious is insistent that he remember something of importance that he must tell the boys. He writes down the numbers 454895. As his brain starts shutting down, Bobby struggles to confront his worst memory in order to regain consciousness. He manages to long enough to write the numbers on Sam's hand, although it appears he may only write the first five numbers. With a final affectionate "Idjits", Bobby dies.
