Red Dragon: Apple!
Discord: I feel pretty!
Twilight: WTB Discord!
Pinkie Pie: You made Fluttershy cry!
Rainbow Dash: Best girl wins?
Applejack: Ah ain’t about to lose to a showgirl like you!
"F-Fancy Pants! Fleur Dis Lee! W-what are you doing here?" asked a panicked Rarity to the most powerful couple in Canterlot. Spike just rubbed the back of his head awkwardly.
Spike sat in the dark cave, alone with his thoughts.
"Have a jub jub fruit!" chirped the small crimson dragoness, holding the apple shaped fruit in front of the surprised purple drake.
Twilight's jaw dropped as she stared in horror at Discord in a dress. one of her best dresses.
"That wasn't very nice Gilda!" chided Pinkie Pie to the griffin "Making Flutters cry like that!"
Rainbow Dash grinned, eyes locked with her friendly rival's own, neither breaking their intense glare.
Just a quick guess, are the 3rd/4th panels from the anime with the Vash guy?

Shockwave: Is that...is that my G1 self?
G1 Shockwave: Indeed. This is a weird day.

Pony Twi: "So... Hands huh? Now what are those round things on your chest?"
Antro Twi: "They're called 'breasts'. And if you don't mind, stop staring at them."
