I don't have a lot I want to say about the Make Your Mark special, but I do have a couple thoughts looking to get out.
This, then, is truly the end of G4. No doubt it's not entirely the last time we'll hear about the Mane Six—Sunny remains a huge fan, after all, and while it's unlikely that Twilight is still around it's not impossible—but it is the last time they'll be the primary focus of a story. It's time to move forward.
While I wait for ever-delayed comics, I'd like to talk a bit about something that is at best pretty tangentially related to MLP (and I won't insult you by pretending that the details of such a justification are in any way relevant): it annoys me when people say "That's not love" to dismiss a dysfunctional relationship. It's overly reductive and it obscures the actual problems.
I realized there's another notable moral one could draw from everything that happened with the Elements of Patriotism. It's one you likely won't notice without some thought, a fridge moral if you will; normally I'd say that a moral that takes effort to find is no moral at all, but in this case I feel it's significant enough to break that rule.
Though, like what I said a little over two years ago, that's not exactly true. There's still the Generations comics—people who aren't incessantly complaining about slow shipping already have one of those by now—and of course it's a safe bet that when we get more G5 we'll also get more references to ancient Equestria. But endings are still endings, whether or not they're total.
