The Child is E.T.
Season 2 of The Mandalorian gets set up by the Armorer as she makes Din’s signet: a Mudhorn. It turns out the Creed is very specific about Foundlings. If a Foundling is claimed by a Mandolorian, that Mandalorian takes over parenting duties until the Foundling comes of age and takes the Mandalorian Creed itself or the Foundling can be returned to its family/culture. The Armorer is the only character in the whole series who remembers the Jedi, and is the first person to bring them up in association with The Child’s Force powers. In the conversation, Mando suggests the whole species has Force abilities, which we’ll have to take as canon until we hear otherwise. All three members of the species -- Yoda, Yaddle, and The Child -- have been Force users. The Armorer mentions the Mandalorian wars with the Jedi (which is when the Darksaber was reclaimed from the Jedi), but says not all Force users are enemies. Which... is a leap. Outside of Kanan training Sabine Wren and Obi-Wan Kenobi falling in love with Duchess Satine, the Jedi haven’t been great to Mandalore, and it sounds like the whole race got wiped out while the galaxy was waiting for Luke to save them... oops.
The Armorer has a mission for Mando: return The Child to its home planet. Which is a huge promise in Star Wars lore. We weren’t supposed to get more of the Yoda species at all if George Lucas had his way, and here we are promising to eventually end up at the home planet of Yoda. YODA PLANET. The Mandalorian 2: Search For Yoda Planet is supposed to hit sometime in 2020, and our Mandalorian and his son have both geared up for it. They wear each other’s signets (Baby Yoda earning a Mandalorian signet necklace in the last scene to go with Din’s Mudhorn signet), and Mando finally gets his jetpack he longed for the last time he left Navarro.
Cara Dune and Greef Carga both decide to stay on Navarro, meaning they can pop up when and if the Mandalorian needs some back-up in the new season. Or maybe they’re not as safe as they think since they’re unaware Moff Gideon, armed with Darksaber, has survived. We also have Boba Fett (or someone in his armor) over on Tatooine, where Fennic Shard is probably not dead. And there are those space pirates that Mando locked away in prison, waiting to come back for a return appearance.
Mando has a fantastic aerial action sequence where he fights Moff Gideon’s TIE fighter and forces it down on Navarro. The sequence is so well placed that we completely forget that we never got an answer to why Moff Gideon wanted The Child. Presumably the technology of cloning plays some factor, as it was introduced in this season then never addressed again, but -- as we’ve been warned -- cloning the Force means talking about midichlorians, and nobody's got time for that. Maybe The Child is the key to finding the planet of Yodas, like another alien who has a healing touch: E.T.!
If you’ve ever ridden the E.T. ride at Universal Studios, you’ll know that the ride ends with you going back to E.T.’s planet, where his healing touch brings the planet back to life: The foliage turns green and a bunch of baby E.T.s frolic around. That seems like the arc The Mandalorian as a series is taking. It was bold to introduce The Child as a character in secret, and now that we know the concept of the entire series has been shackled to this character that doesn't get a name in the first season, the ending has to be The Child’s return to the Yoda Planet, right? You still can’t kill Kid Green, so that’s our only option. How many side adventures can Mando and Mudhorn go on before the series needs to give us a conclusion and bow out on top? Four seasons?
