The Walking Dead is a love story, Clementine is merely the backdrop.
The game will end with Ben and Lee finally professing their unspoken love for one another, Ben's kiss of true love will then cure Lee of his Zombie infection, and the two will raise Clementine happily ever after.
Or, if you let Ben die/left him behind, the game ends with Lee turning zombie and eating Clementine.
Either way, Ben will ruin your game.

Best ending: Everyone lives, gets on the boat, but Ben with his incompetence falls off the boat and drowns. The credits then roll and instead of an end-game stats screen, a black screen appears with the sentence: "Ben drowned" in Brush Script STD font.
Then the next time you play the game you get the message "Dawn of a New Day" and a creepy statue that looks like Lee keeps teleporting to your location. Then you hear the voice of Hershel from Chapter one screaming "Get the **** out of here!" and the game resets.
