Don has the franchise problem now: not only he has to untangle his story knots, he now has to compete with all these fan theories and expectations (I do love reading them though, so keep it coming!)
My expectations is that it will be Lester who bails Dan out of jail. I always thought Dan-Lester relationship is too adversarial and it will be easy for Dan to pin his misfortunes on him. I would've liked to see Lester be occasionally fake nice to Dan, especially in front of Sarah, as a part of his manipulation. May be this time during their pillow talk (fingers crossed!) He might promise to help Dan with is job search(BS, obviously) and then he rushes to bail him out. When Dan returns and express we his doubts about Lester, he'll be facing pushback from her.
Also +1 on Jesse been thrown out.
