So everyone expects a lot of dead bodies, Hank among them because of the "I love you" - and BB has been known to mess with expectations (hint: Walt's "confession tape")
But there are however a few annoying plotholes:
-Walt had to assume his rented car had GPS. They all do..right?
-Walt owns a car wash. Why the hell does he hand over the car to Sauls bodyguards to wash it?
All so it could lead up to events in this episode? Or am I missing some stroke of genius?
