Something to make you happier
I don't know if this will make you happier. But it could be considered headcanon.
Okay, so we know that The Walking Dead video game series is canon with the comicbook universe. In the video game series, Lee dies and Clementine is left alone by the end of Season 1.
However the television show is not canon with the video game series, due to differing events. Therefore it could be entirerly possible that things worked out better. Larry may not have died. Lilly may still be running things. Lee could be in a romance with Carley, whilst Clementine is alive. Kenny could still be with Katjaa and Duck. There's nothing to say otherwise, since many of the characters in the television show (Rick, Andrea, Tyreese, Michonne, Glenn, Maggie, etc.) exist in the comic book universe - The same can occur with the game and show.
I'm not saying the show will feature Clementine and Lee, though a crossover has been something that Kirkman has said would be "always open for us". However "whether or not we step through it remains a big question". Not only that but showrunner, Scott Gimple is "a huge fan of that game series". It's always possible.
But if you're ever sad about the events that occurred in Season 1 and that Clementine is alone. Just remember in the television show, things may have played different. It's a nice thought at least.
