Todd is one of the creepier characters in the show. I love how he happily chirps "You got it" when Heisenberg put out the hit on Jesse.
New prediction:
The flash forward was Walt returning to town to recruit Jesse the Judas because Jack and the rest of the Aryans wouldn't take "i'm done" for an answer no matter how much Walt helped them.
In my opinion the following scenario is probable:
Hank and Gomey are dead
Neo Nazis abduct Jesse and use his life as a bargaining chip to compel cook for them
Walt flees town and comes back as Mr Lambert
Epic showdown between Walts machine gun, air dispersed ricin?, and the neo nazis
