No one should feel bad about the spoiler on it's own, the show has been off the air for nearly a decade. It's the fact that spent all these episodes providing no spoilers at all, then on the last episode they gave what I'd assume is the biggest spoiler, on a throwaway line, it was sloppy. Jimmy could have easily said "Jesse Pinkman is still out there" leaving some mystery, to those who haven't seen the show, about what happened to Walter. Did he become a snitch, is he in jail, is he dead?
I'm going to watch BB, hopefully, someday.
