Walt's transformation is complete.  He acts exactly like Gus did —- from trying not to break character" at the car wash to even putting down the towel before he throws up in the toilet (like Gus did at the cartel's home).

If the show comes back, Jeff should come back as a professor. Like in Welcome Back, Kotter

Pretty amazing episode.  The review summed it up well:  Perhaps the best since the Pilot.
