All of this.
Their names will become legend and when Jesse is gone and he changes his name and identity, he will go down in history as the right hand man to the great Heisenberg. In the golden age of meth. Stories will be created: maybe they were in it all along? Did you hear that Jesse used to be his student? I heard Jesse pulled the trigger on him and took the rest of the money for himself! People will try and imitate the blue meth and nothing will be the same, or as good. And just like the meth, Jesse and Walt will never be seen again. Like it was all just a bad bad dream.
