I was really disappointed that they wasted one of the last episodes on this dreck. It was boring. There was no connection to the guest characters. If it advanced the kill Chuck story, in some way, I didn’t see it, Dean chatted with Billie in a diner. Sam and Dean argue about stuff in the car. If the stand alone story had been well written, I wouldn’t have cared. I think it sucks that at the end of this series, it’s mostly just phoned in.
