How had they even met... exactly?

Pinkie Pyro: (giggles) "You'll get a sore throat, silly!"
CODA: "Stop... (licks ice-pop) ...calling me (licks again) ...silly, you silly one, Pinkster or what your name is. I am immune to this kind of disease, because I got used to all my body aching every day!.." *lick*
Twilight Sparkle: (in her thoughts) "Am I really going to become a monster, someday? Going to lose my wings like in that insane My Little Portal thing?.. And what will happen... to my eyes?!"
