DISCORD: "Ah yes, Eye of the Fluttershy. I must say, Fluttershy, once I looked back and saw this moment, I was quite moved, you know. You really did very well, pushing yourself that much. And you look so cute when you're working out too!"

Scale of Ratings

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?

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."

RAINBOW DASH [sighs blissfully]: "The only thing that could have made that moment any better was if I had been able to go into the book and join Daring Do on her adventure!"
DISCORD: "You rang? That can be arranged quite easily, my dear Rainbow Dash."

SWEETIE BELLE: "Wow. You just had to pause on that frame, didn't you? Look at my face! I look like you're creeping me out!"
RARITY: "You? What about me?!? Need I remind you that I ran an obstacle course covered in mud for you, my little sister?"

GRANNY SMITH: "Eh, what were we hugging for here again, Apple Bloom?"
APPLE BLOOM: "Don't ya remember, Granny Smith? I had a crisis of faith and didn't want to bring you to school, so I pretended to be sick, tried to speed up the harvest, controlled you while you were asleep, and faked a message from Uncle Apple Strudel!"

FLUTTERSHY: "You know what they say, my poultry friends. It's always the quiet ones. You don't want to know what I'll do when I get really angry. Let's just say a dragon made me angry, and he didn't like what I did."

"Listen up, dweeb, it's not my fault they never brought me back after Season 5. That doesn't make me any less important then the other originally-one-time character from these pair of episodes! You got that, you pink puffball?"

RAINBOW DASH: "I look like I have a mohawk blowing in the wind, don't I? Yeah, I think I just got about 20% cooler."
FLUTTERSHY [off-screen]: "What? But, um... I thought you said it was lazy and uninspired to just quote fan-loved moments for these intros..."

TWILIGHT: "Winter Wrap Up, Winter Wrap Up, our song is so iconic that even the show itself referenced it twice in Season 4!"
