- Fanfic Fuel:
- The full details of Rockhoof's showdown with the Ursa Major.
- Now that the Pillars have found new callings in life in the modern age, what will their lives be like now? After all, with the exception of Flash Magnus, they initially came back with the intention to help defend the land and their current jobs could be a case of Heroes Gone Fishing.
- Since Flash Magnus became the Canterlot Royal Guard's newest drill sergeant after the events of "Shadow Play", how did he fare during the Storm King's invasion? Did he fight Tempest Shadow?
- General Seaspray suddenly has scars all over his body unlike his debut. What could the Mount Aris Navy possibly be up to that would warrant such a result?
- Fanon: Fans and reviewers often interpret that Flash Magnus replaced Shining Armor as the Captain of the Royal Guard with the latter being busy in the Crystal Empire despite Twilight clearly stating that he was just the newest drill sergeant.
- Hilarious in Hindsight: The idea Yona would idolise an older fellow that likes smashing as much as she and the Yaks does is explored in this comic.
- Idiot Plot: The plot keeps moving because Rockhoof gives up at every new venture at the first setback, instead of trying harder or learning from his mistakes. The Mane Six in turn suggest jobs for him that are at odds with his personality and skillset and don't put much thought into their ideas. There are plenty of career opportunities in Equestria for someone with great physical strength and a passion for digging, several of which should have been very obvious, but no one suggests them. Additionally, the plot begins in the first place because Rockhoof isn't welcome at his old village, which is now an archeological dig site — Professor Fossil just sees Rockhoof as a nuisance and doesn't seem to realize that the pony who actually lived in the ancient village she's excavating may have a lot of helpful information to contribute, chalking it up to the fact that they need the full context for archeological digs.
- Informed Wrongness: Rockhoof putting out the fire in the school from the outside when it turns out that it was a dragon fire-breathing contest between Spike and Smoulder. He was supposed to be in the wrong for being an ignorant killjoy and damaging a lot of quilts that don't do well with water. The problem is that 1) the contest was held indoors instead of outside when the classroom in question was not proven to be fireproof and 2) without context, when viewed from the outside the fire generated could easily qualify for a fire hazard as it was the size of a whole classroom and any sane being would had done the same thing as Rockhoof did.
- Take That, Scrappy!: After Cranky Doodle Donkey's Jerkass Ball scene back in "A Matter of Principals" (treating the friendship students like servants, and repeatedly spitting iced tea in Gallus's face for not making it the way he liked), him getting publically humilated by Rockhoof yelling to everypony in town about the rash Cranky has in an "embarassing place" makes for some decent (if slightly overdue) comeuppance.
- They Wasted a Perfectly Good Plot:
- Applejack is mostly relegated to background appearances in this episode, and Apple Bloom doesn't appear at all. Given that Rockhoof is the hero of their favourite childhood story, you'd think they'd have more to do here. Furthermore, Apple Bloom's special talent is helping other beings find their talents and destinies. Her helping Rockhoof find a place for himself in the new Equestria would seem to be a natural place for the plot to go. Not to mention the Apples live on a farm, where Rockhoof's digging talent and physical strength would be invaluable.
- Despite Rockhoof's similarities to a yak being a plot point with Yona's adoration of him, no one thinks to see how he'd fare in Yakyakistan, where his behavior would be much more welcome.
- It's implied that unlike Mage Meadowbrook, Mistmane never revisited nor kept in touch with her old home and descendants back in the Season 7 finale before deciding to be the Crystal Empire's royal landscape artist.
- Unexpected Character: No one predicted the return of General Seaspray in this of all episodes. And while Rockhoof was obviously going to appear, the rest of the Pillars (besides Star Swirl) came as a surprise.
- What an Idiot!: Spike and Smoulder held their fire-breathing contest indoors instead of doing it outside. Not to mention, Rarity was there to supervise them thinking that this is a good idea. No wonder Rockhoof thought it was a fire hazard.
- What Do You Mean, It's for Kids?: Rockhoof wanting to be turned to stone when he can't fit into the modern age is a blatant allegory for contemplating suicide, which is decidedly dark for a show supposedly targeted at young children.note Becomes even more disturbing as Twilight seems quite willing, though reluctant, to go through with it.
- The Woobie: Rockhoof, especially by the time he wants to be a statue.
