Say, those names sound familiar…

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!"

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]

APPLE BLOOM: "...Do you reckon this is an accurate depiction of how these episodes are written on a weekly basis?"
SCOOTALOO: "I don't know about that, but this certainly feel like an accurate depiction of how the cold opens for these reviews are done!"

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?"

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."

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?"

TWILIGHT: "Wow. It's like looking in a dimensional mirror. Is this a version of me in an alternate timeline of Equestria where we're at war? Or in a resistance? Or where we lost to Nightmare Moon?"
FUTURE TWILIGHT: "...Discord! Have you been mixing visions of alternate timelines into Present Twilight's subconscious dreams again?"
