10 Greatest Unspoken TV Plot Points
7. The Connection With Gravity Falls - Rick & Morty
Rick and Morty creator Justin Roiland and Gravity Falls creator Alex Hirsch are the best of friends. Because both cartoons have similar characters, plots, and humour, Roiland thought it would be funny to incorporate elements from Hirsch's work and vice versa. Throughout Rick and Morty, you can see Dipper's 3 Journal, Bill Cipher, the talking chair that Ford encountered, and alternate reality Mortys who are modelled off Dipper and Mable.
Now, just because elements from one show appear in another doesn't necessarily mean they're connected. Nods like this are usually throwaway gags that shouldn't be considered canon.
But since Roiland and Hirsch are so tight, it's safe to assume the Gravity Falls gang do exist in the Rick and Morty multiverse and are more connected than they seem. Ford's journal contains a silhouette of a Zigerion (which Rick encountered when he met Prince Nebulon), implying the two scientists have mutual acquaintances (as well as mutual enemies). Because Ford is a super-genius who spent years hopping through different realities, it's feasible he and Rick are aware of each other.
Although the references to Gravity Falls are appreciated, we're hoping the characters are officially acknowledged in the future.
