Adult Swim released a Rick and Morty mini-episode that attempts to reconcile the seemingly infinite interdimensional timelines that were introduced over the past six seasons.

Here are the trailers for the seventh season.
Here is one of the most profound scenes referring to the timeline from the first season.
