Lee's totally alive! He gets saved by Carley, who's feeling much better after having a relaxing nap in the road and has been tracking him all this time. Not only that, but the zombie plague has been cured! The first chapter of Season 2 is all about Lee and Carley's wedding, and everybody comes, including a lot of other people who turned out to have survived, such as Kenny, Ben, Duck, Katjaa, Chuck, Doug, Larry (who had a change of heart and became nice), Mark (whose legs grew back) and Lee's parents and brother. Daryl even make a special guest appearance to give them a big wedding cake he made out of squirrels. Then the RV drives up, loaded with wedding presents, and Lilly gets out and apologizes to Carley and they become best friends. DJ Doug rigs up an awesome sound system and everyone has a huge dance party. Afterwards Lee and Carley adopt Clem, even though Clem's parents are still alive, too, and then they have seven more babies, which all become best friends with Omid and Christa's baby. Then Guybrush Threepwood shows up and reveals that he was the one who cured the plague by using La Esponja Grande.
Seriously, that's exactly how it's going to go down, just wait and see.
