Gus Fring meets his end at the end of Season 4 of Breaking Bad.

This may have been our favorite scene of the Breaking Bad finale. Jesse and Walt leave the super lab for good.

Walt and Jesse bid farewell in this scene from the season four finale. We have a feeling they'll find their way to one another again, though.

Walt and Saul have come a very far way together. Will they both live to see season five?
