First episode, the Main Six prepare for a race where they build carts for their pets to drive. Although it's supposed to be just for fun, Rainbow and Twilight immediately get very highly competitive, pushing their respective pets to win. Once the race is underway, Tank and Owlowicious are so determined to win that they end up wrecking all four of the other carts in their wake. Thankfully, they notice the carnage before reaching the finish line, and turn back to help their competitors cross the finish line at the same time. This result forces Twilight and Rainbow to apologize for being too overly competitive.
Second episode, the Cutie Mark Crusaders are excited for opportunities to earn badges for their Trail Trotters Troop (FYI, that was the troop name I couldn't remember from last week's episodes). Despite some reasonable suggestions from the others, Rarity insists on performing a magic show, blatantly ignoring everything from her friends' discouragement, the CMCs eager to volunteer, her friends not agreeing to "volunteer", and Twilight's concern about using three potions at once on all of them. As a result, Rarity is horrified when she accidentally send her friends into "the void", and when the CMCs look up information on the potions to discover it was the result of Rarity's ignorantly selfish behavior, she repeats the trick on herself and brings her friends back with her.
Third episode, while Pinkie is saddened that her oven breaks down and has to be junked, Twilight arrives with a new machine that requires some extensive assembly. She's confident in her ability as the self-proclaimed "master of instructions", until she discovers the absurdly long instruction sheet consists of nothing but a bunch on incoherent diagrams with no labels at all. After she and her friends despair over those confusing instructions, Twilight decides to just make her own instructions, and cheers up Pinkie by asking her to help out. In the end, the completed engineering project turns out to be a new oven for Pinkie.
Fourth episode, Fluttershy is eager for her next attempt at a Trail Trotters Troop badge (for which her friends still haven't told the truth to her) by hiking up a volcanic mountain with her friends. She also insists on inviting Discord to join them (despite her friends' opposition to the idea), but Discord refuses to go due to simply being not interested. The Main Six eventually reach the top of the volcano, but Fluttershy is so desperate to have Discord join them that she tosses Pinkie's dessert monstrosity into the volcano, intending to start an eruption that would be chaotic and exciting enough to attract Discord. But now with the lives of her friends at risk, she quickly realizes she made a terrible mistake, though thankfully Discord shows up and stops the eruption. With Discord still not interested in joining her efforts with the Troop, she lies about the existence of a "Solo Scout" (though it's not lost on the others how that reaction is very much like how they've been lying to Fluttershy about the Troop, which they still refuse to admit the truth).
So it seems that it's Rainbow and Twilight who tend to be highly competitive in this series, rather than Rainbow and Applejack from FiM. While it was nice to see the Cutie Mark Crusaders again, seeing Rarity pretty much behave just like Trixie really brought down that episode (though it's good that her friends eventually called her out for her awful behavior, I'm sure some fans would have rather seen Trixie herself fill that selfish role more appropriately). I mentioned previously how Twilight had so far been the only Main Six pony to not have an episode focused on her, and it looks like this one where she struggles with instructions might be that first such episode. And finally, we also got to see Discord again, and although he's got a different voice actor (kinda makes him sound a little British), he's still very much the same as we remember from FiM (though it seems here Fluttershy has become far more obsessed with having him around, to the point where she outright ignores any worries from the rest of her friends). Overall, while it was nice to see Twilight finally get some attention, I still don't like how Fluttershy is being treated like she could get away with anything.
