Applejack: "Big Mac, what are ya doin'? You're only supposed to pick one header image for these darn things!"
Big Mac: [eyes dart down, then back up]

LIGHTNING DUST: "Say, you really were a strong flier up there, Rainbow Dash. Almost as good as me! You admiring my skills too?"

Sweetie Belle: "This is it, girls. This dress-up princess contest is finally here. We've been preparing for it, practised all our moves, and learnt how to trot without tripping on the hems of our dresses. You ready to wow the crowd?"
Apple Bloom: "And then maybe we'll finally get our Cutie Marks!"

CHRYSALIS: "Finally! Ugh, that Nightmare Moon was too bland, and Discord jokes around too much. Time for you all to see what a real villain is like!"

APPLEJACK: "Was there even any doubt as to the image for this cold open? This Apple Family photo here inspired so many countless similar photos of Bronies at conventions globally, it'd be a disservice to do anything else here."
APPLE BLOOM: "Ooh! Does that mean they're still taking photos like this these days too, sis?

CHEERILEE: "Don't get me wrong, I do love my students, but it's so hard finding ways to dispose of the overblown gifts they sometimes give me. I mean, what am I supposed to do, keep that thing in my tiny house? Not happening. Hey, don't judge me, at least I keep their gifts long enough for them to forget before I dispose of them."

Rarity: "…Let me guess, one of today's episodes prominently features you?"
Rainbow Dash: "Heh, actually, they both do! But don't worry, you get in on the action in one of them too."
Rarity: "Oh! Another episode pairing us up? That can only lead to unexpected things. Do tell, Rainbow Dash."

APPLE BLOOM: "...I don't get it. Why this screenshot? It's not an especially memorable moment or image from the episode, nor does it sum up what it's about."

TRIXIE: "But... I... how did you... wait. Is this pose being used as shipping fuel for a Twilight-Trixie pairing?"
TWILIGHT: "If you like, Trixie. Not my intention, but we have to appeal to the fans that make content sometime, you know. Besides, I thought you liked being a waifu?"

DISCORD: "Oh Twilight, you are a card! Why is it that you're always so glum and serious whenever I'm around, when you had this level of chaos in you? Oh, the things I missed in nearly 1.5 seasons of being in stone!"
TWILIGHT: "Discord... would you like to find out whether the 'Want It, Need It' spell works on draconequi?"

Rarity: "Courtroom drama or detective spoof? Who says one has to choose over the other, darling? Both are fabulous enough to get their chance to shine."

TWILIGHT: "Sunshine, sunshine, ladybugs awake. Clap your hooves, and do a little... what's wrong Cadence?"

DISCORD: "I'm back!" [laughs] "Speaking from the shadows is very good, don't get me wrong - I like a good challenge as much as the next draconequus - but being an actual character in the show again just gives me so much more room to work with for these! Wouldn't you agree, Fluttershy?"

APPLEJACK: "You know, Sugarcube, that Dragon Code thing of yours sure did seem to come out of nowhere. How come you never brought it up before?"
SPIKE: "Oh, uh, well... you remember when we watched the Dragon Migration?"
APPLEJACK: "Personal crisis?"
SPIKE: "...kinda."
APPLEJACK: "Decided to join the migration?"
SPIKE: "Yeah."

SCOOTALOO: "This is the Best Flight Ever! Am I right?"
RAINBOW DASH: "Heh, maybe, squirt. It's no Sonic Rainboom, but this is pretty cool. Although, is this your first time speaking for one of these? It's just, that nod to 'The Best Night Ever', it needs to be about..."
SCOOTALOO: "...Twenty percent cooler?"

PINKIE PIE: "Yeah... probably not my finest hour here. Making copies of yourself to hang out with all your friends at the same time - let's just say it's not nearly as fun as you might think!"

Rarity: "Stop the presses! It's Wednesday evening! Mike Cartoon Pony is posting another blog on unused Season 5 episodes! Forget these dresses for a client coming in an hour, this is The. Most. Important. Thing!"

Spike: "This thing again, huh? Going right in with the episodes locked to a formula, I see."
Applejack: "Wow Spike, that's mighty insightful of ya. How'd you deduce that so quick?"
