[SPOILERS] We begin with a stunningly animated dinosaur meeting its fate as a giant meteorite is about to wipe out all dinosaurs from Earth. The seriousness breaks as the documentary is paused. Frankie and Elliott wish to tell Mo about the dinosaurs extinction on Earth, since Mo is from it, too; but the film was not meant to explain the extinction to dinosaurs. We then get to a few jokes caused by the other bad ideas of breaking the news: a space banner and dinosaur comics. Mo believes dinosaurs had laser arms and protected the Earth from a toy that says “Eat laser, alien vermin!”. Not really appropriate to tell a class of aliens. Mo then shows up and apologizes for dinosaurs eating people at a theme park, thinking of Jurassic Park as fact. Elliott finally tells Mo the truth, which makes the latter cry. 3 minutes in, so far so good. Mo roars at Elliott and runs away. Things go from sad to tense immediately, as we see everyone in the Centrium blabber in different languages, instead of normally understanding each other. Another good mix between comedy, seriousness, sadness and problem solving. We get to the Hive, where the alien passionate about linguistics tells Elliott and Frankie what happened: the Babbledrogs stopped creating language for the Centrium. We get more plot explanation as we go on past the 6th minute. The glowing meteorite was attracting Babbledrogs to take their electricity. It is cool that Elliott and Mo apologized to each other and got along again. Elliott learns Mo was sad about having had lied about dinosaurs, and not about being the last dinosaur, because Elliott, Frankie and Mo were all from Earth. Before everyone gets to be happy again, Frankie and Mo reactivate the mysterious meteorite, which tells us Mo is actually not from Earth. It was a powerful enough reason to end a chapter (Chapter Two) and the entire season. It is sad that Elliott and Frankie got separated. A strong 10/10 for telling more about the rock lore and for leaving room for future episodes, if any will ever be made.
