Maybe I have this timeline wrong. Let me know if so, please.

Hurley sees Charley in a bodega, crashes his Camaro in a police chase, and gets recommitted to Santa Rosa by AnaLucia's former partner, where he starts regularly chatting w/Charley on the front lawn. Charley tells him that someone is coming soon to see Jack. Hurley's doctor tells Jack that ttreatment isn't working anymore because Hurley doesn't believe that anyone there was real--except for Jack and Charley, apparently. (Does he think he's still on the island? Still in Jacob's cabin?) Hurley is near catatonic when he tells Jack that Charley told him someone is coming to visit Jack. Now, at some point, Hurley gets better, or at least he recovers enough that he's alert and coherent and responsive in the near future during a game of horse with Jack, during Jack's second visit. Hurley was even lucid enough that he already knows (before Jack does) that they have to go back to the island.

At the same time that Hurley gets better, however, Jack was gets worse and worse. Remember during horse, Jack already had a beard and was a little skittish! He was drinking during the day (drank while watching Hurley's police chase on TV).

What helps Hurley finally start to come out of his craziness?
