I dunno breh. I think Skyler is dead. Look at the clues....
Krazy 8 died, Walt started cutting the crust off his sandwiches like Krazy 8.
Walt kept the eye ball from the plane crash.
Mike orders his drinks with ice, Walt never did.
Until he killed Mike.
In that future scene, Walt is driving a Volvo. Gus drove a Volvo.
In that future scene, Walt is arranging his bacon like Skyler used to. Also, he called himself "Mr. Lambert". Lambert is Skyler's maiden name.
She's dead yo.
Walt dying is a given at this point. I'd be surprised if he doesn't die.
Fred.
