Screw it, I'll just do my usual thing for the rest.
- The montage music is totally based on "You're The Best Around"

- Okay, what the fuck are trees made of in Equestria? Between this (Fluttershy crashing right through one in the montage like the dragons did twice last week) and the tree costume and Rainbow Dash's eyeball gag, I'm really starting to wonder—are they all hollow? And made of papier-mache?
- Oh holy hell I missed the gag the first time with her eyes sucking the tears back up (accompanied by a drinking-straw sound effect). GOOD LORD

- At the end of the montage she goes straight from

to

HNNNGGGG Best sports training montage ever. And interestingly, everything that ever attempts to do such a thing following South Park's "Montage" song necessarily has to do it as a self-aware parody to some degree; the way this is handling it is with the gleeful, joyful girliness of it—her mark of success is that she goes so effortlessly into a face like ^^ that. I love seeing her in her comfort zone again, especially after having shown us so forcefully how far she has to climb to get there.
- Egad:

Right after Dash goes "Cloudsdale still needs water", Twilight does this little half-foreleg-flourish
with just one leg before running off. God dammit I'm overloading again
- Hah, okay so we haven't had much this season of Applejack grabbing Rainbow Dash's tail in her mouth, but we've had at least a couple instances now of Twilight taking over for her. I love Dash's squawk of annoyance when Twilight latches on with her magic.
- The water arcing through the air into the receptacle evokes a rainbow. Rainbows have been used enough times now in situations like this that they've become emblematic of triumph.
- Aww, I like how when she says "anypony's contribution, no matter how small", it cuts to all of Fluttershy's little animal friends cheering her on.
I don't know if I can quite express how much I love the whole concept of this episode's setup, with the whole "get water into the weather factory" thing. Every bit of it makes perfect sense in-universe and expands on ideas we've seen expressed before; and at the same time it's little more than a MacGuffin to allow Fluttershy to have her character development arc, which is the real meat of the story.
I've really been enjoying the last few episodes, always feeling like they've kept consistently raising the bar of awesomeness; but really, compared to this one they feel awkward and almost forgettable. This thing was a damn masterpiece.
