Eenie meenie miny moe ... One of these remaining survivors will replace  Jacob as the island's protector. Will it be Hurley, Jack, Kate or  Sawyer?
The penultimate episode of “Lost” saw a return  to form Tuesday night, which means there were plenty of familiar faces  and absolutely no signs of last week’s crazy-island-mama drama. Good  thing, too. After all, viewers still have to contend with two different  realities, conflicting body counts and a laundry list of unsolved  mysteries. 
Not  that any of those long-term head-scratchers met their resolution. No,  this glimpse into the ongoing unknown simply set up the action for the  finale night’s big bang and teased at the ongoing mini-mysteries. 
Why? The alt-action  alone was enough to explain the forward momentum, and the on-island  segments reinforced it. 
Back in Los Angeles, where Jack, sister Claire  and his son David were busy playing alternate-reality house, the good  doctor received a call from an Oceanic rep about the recovery of his  father’s missing coffin. Nice timing, only the call didn’t really come  from a rep. It came from the ever-crafty, other-reality reminder,  Desmond. 
It seems  Desmond was still a man with a single mission: remind and reunite his  other-reality pals. To that end, his next prank-with-a-purpose started  when he showed up at the scene of his last crime, the high-school  parking lot where he plowed down Locke.
Conveniently enough, Locke, fresh from his  hit-and-run vacation, wheeled in front of Desmond, who looked tempted to  repeat his violent performance. That is before Ben Linus, of European  History fame, stepped in to stop him. 
Rather than give Ben a drawn out explanation about  how Desmond’s really more interested in jogging Locke’s memory than  killing him, Desmond gave Ben a hands-on example by beating him into  remembering his other life. The pounding served a second purpose for the  professor, who later scored a sympathy dinner with Alex and her  remarkably hot mom, Rousseau. 
For Desmond there was more work to be done, so it was  off to the LAPD, where he confessed his crimes to Detectives Ford (aka  Sawyer) and Miles Straume. The act earned him a spot on a van to the  county jail, conveniently situated alongside Kate and Sayid. In other  words, just where he wanted to be. 
With the help of a cop on the take (Hey, Ana Lucia!)  and Hurley, Des and his new-old pals were free and ready for stage two.  What’s stage two? All signs point to a big alt-world reunion for the  would-be and once-were friends at the benefit concert for Pierre Chang’s  museum.
Elsewhere on the island,  Jacob took solid form  long enough to meet with the four remaining  candidates in line to  replace him. Yes, four. Jack, Sawyer, Hurley and  Kate, whose name had  been crossed off the list earlier. 
According to Jacob,  crossing off a name is just a  matter of chalk lines. Kate was a mother  for a brief while, so he took  her off. She was welcome to stay in the  running — if she wanted to. In  fact, despite how important Jacob’s role  as protector of “the light”  is, each of the candidates had to make the  choice to follow his lead or  not. 
One of them  could step up as the new island big shot,  or they could all walk away.  It wasn’t a safe choice, but technically  they had free will. 
That’s all  Jack needed to know. When faced with  the choice, the new man of faith  decided it’s the role he was always  meant to assume. After a little  water-into-wine action from Jacob, Jack  did just that. 
That’s  all there was to  it. Well, that and some expert snarking from Sawyer:  “I thought that  guy had a god complex before!”
