What if in this turn of the wheel, Roland remembers Jake and what happens with him, and knows that TMB and CK are going after him before Roland finds him to use as a breaker? Roland knows this, he's got the horn after all, and we've seen that he CAN remember snippits from one cycle to another. What if this time he remembers a bit of Jake? So he's searching for a door to get to NY to get to Jake before TMB can get him as a breaker? Kinda like that. Then that would explain bringing in Pimili and the other low people and the Tirana chick, etc, so early. Roland saves him from TMB but still sacrifices him in order to get more info from TMB. Movie ends with Jake dying, Roland moving on to drawing Eddie and Susannah and maybe Jake again in movie 2?
