Walt, seeking long overdue respect from his former Grey Matter partners, breaks in and holds Elliot and Gretchen at gunpoint. He extracts a unknowing confession from Elliot that proves that he contributed more than just the name, and he now is entitled to 1/2 of Grey Matter. He had overlooked this little detail in his ego driven rage-quit years back. His family is now set. As he is standing there holding the key to his family's security and happiness, legions of law enforcement close in around him. He contemplates shooting Elliot in the face and using the ricin in his pocket to end it all, but before he can pop the vial into his mouth, he begins to hack, passes out and dies.
