Adult Swim was always a strange place on the Cartoon Network. Generally, shows on Adult Swim took advantage of the sudden shift from G-rated to nigh R-rated content, but that was about it. One show that has become more than just a guilty pleasure is Rick and Morty, a cerebral comedy about senior citizen scientist Rick and his grandson Morty as they go from one science fiction setpiece on other planets, dimensions, and timelines. Season 2 of Rick and Morty ended on a bit of a cliffhanger, which is extremely rare for that show to have any continuity, but this is what is known about Season 3 release date and story news.
As mentioned before, Rick and Morty is one of those shows where things just kind of happen. There have been episodes that reference other episodes, but for the most part, it doesn't look like there is any story going on. However, it has been revealed from creators Dan Harmon and Justin Roiland (the latter voices both title characters) that there is a plan for the show, but it is quite subtle.
The creators know that the show has a huge fanbase, and they are working their hardest to make certain episodes are up to the quality standard that fans have come to expect after two seasons. The creators also intend to do episodes that will build upon each other, but it is not known what the big plan of the show is.
For those that are familiar with the show, there has been several episodes that have addressed that Rick and Morty exist as part of a multiverse. That is, there are several different versions of the same reality, and Rick and Morty have versions of themselves in these respective realities.
As far as Season 3 is concerned, the storyline about Rick being a prisoner has to be resolved so that Rick and Morty can be...Rick and Morty. There is a preview at Comic-Con that showed a series of animated storylines with Rick as some weird insect taking on a lot of rats with a lot of violence. It feels like this is the way that Rick escapes from prison, perhaps?
There is a report from iDigitalTimes saying that a short promo is being created with stop-motion animation. Is it possible that there will be an entire episode devoted to it? Considering that the show is pretty experimental, I don't see why not.
I have said before that it feels like a theme for the show is how one faces individuality in a universe full of copies, and it will be interesting if the show is going in some direction of big conflict. In my opinion, it might be good to end the show early before it suffers from being on TV too long, as some of the best animated shows such as Avatar: The Last Airbender and Gravity Falls didn't last too many seasons for the sake of their storyline.
In the meantime, expect to see Rick and Morty Season 3 some time before this year's end.
