I think a comic book timeline would be cool. It'd be interesting with the Telltale games being in that universe, since theres multiple choices. I thought of thinking about it like all the different options are different timelines, but they all follow the "sacred timeline" of Earth-TWD (comics) or something... but then the Clementine book series seemingly confirms that Clementine didn't go with AJ on her own, since she's not missing a finger.
In other words, all choices lead to the exact same events but the ones where she doesn't go with Kenny or Jane is non-canon. We don't exactly know what specific choices are part of the primary timeline, but for the sake I'd argument lets say the most popular.
(Yes, the Clementine book series is trash and spits on the storyline. No, that doesn't make it non-canon)
