My prediction:
Time jump (at least a small one). The episode opens with Hank and Gomez already dead (think Butch and Sundance, and remember how the last episode went to black during a perceptible increase in the firing rate).
Don’t know if Jesse is dead, or gets away, or is captured, but Jack shook hands with Walt on a deal saying Walt would cook if Jack got Jesse for Walt. That’s why Jack showed up, he wasn’t letting Walt out of the deal. Walt might “save” Jesse by offering to cook more than once if they spare him but Walt’s not in charge any more, certainly not in Jack’s mind.
Now, Walt and Hank (and Gomey) have disappeared, Skyler and Marie have no idea what happened to them, though Marie knows that they were together when she got the phone call.
Can they locate Hank and Gomez using the GPS in Hank’s phone or car? Will Jack’s gang bother to hide the bodies? The Car?
I believe that Walt escapes somehow (maybe even with his family, to New Hampshire?), at least eventually; the gang keeps Jesse to cook. Walt returns and plans to use the M-60 and the ricin to go after them and to rescue Jesse.
All of Walt’s moves in the flash forwards (telling the waitress it’s his Bday, showing his ID, leaving a $100 tip for an uneaten breakfast, saying hi to Carol) seem to express an eagerness to be seen, so he wants whoever he’s going after to know he’s coming.
5 hours to go (on the left coast) and my blood pressure is rising just typing this!
Emilio, Crazy-8, Jane, Gale, and Mike are listed in the credits, so there will be flashbacks tonight…
