Here some quotes:
Cozy Glow: [to Ocellus] I mean, growing up as a love-starved changeling? [to Silverstream] Or hiding underwater from an evil king all those years? Trusting anycreature must be so hard for you. [to Gallus] And griffons never want to be around anycreature, even other griffons. [to Smolder] And dragons are so fierce compared to us. There must be days you can't wait to get away from all us cute ponies. [to Yona, imitating Yona] "Everypony know yaks think yaks are best!" Making friends with any other creature must seem like a step down. It's just so impressive how you keep trying to understand friendship, even though it isn't in your nature.
Cozy Glow: You get some rest. Don't give any of this another thought. Just let Cozy take care of everything.
Smolder: Like, why'd she change her mind? Why did Starlight write a note instead of saying goodbye to us herself? Doesn't make any sense.
[students murmuring]
Cozy Glow: [giggles] Oh, Smolder, you forget. We're not scheming dragons. We're ponies. Sounds like somecreature needs to do a little extra friendship homework.
Cozy Glow: You might get some company soon, if I can't make that annoying Neighsay back off! [inhales, exhales] All this magic needs time to drain from Equestria before my vortex sucks it to another realm. [giggles] Three days can sure seem like forever, huh? You know, you ponies got it all wrong. Friendship isn't magic. Friendship is power! With Twilight and her lackeys out of my way, all of Equestria will bow to me! The future Empress of Friendship! [maniacal laughter]
