“Ach, who wants to study Scoltland? The weather’s always cold and rainy, the food’s awful, and all the lads walk around in skirts!” Aw, I’m just joshin’ ya, lass. Don’t get me wrong, I love my homeland. But there’s just something about Zebrica. The culture, the traditions. The mares.”

Context: Rainbow Dash asked how a Scoltish(Scottish) pony ends up being Equestria's leading expert on ancient Zebrica.

“Well, you see it’s not a cutie mark. Zebras are like donkeys or cattle, they don’t get cutie marks. It’s a tribal inscription, means she’s a shaman. That’s why she speaks like that. In Zebrican culture, it’s seen as a mark of enlightenment. All shamans, artisans, and village elders speak in rhyme. The eleven rays from the sun means she’s a master level shaman. Most likely, she started studying Zebrican magic around the same age that you did, lass.” 

Context: Parchment asked if Zecora speaks in rhyme and has the picture of the sun for a cutie mark. His voice is a bit downtrodden, because he doesn't want to cast guilt on Zecora.

“I will not suffer you insects any longer! The power of the Celestial Parents themselves is at my hooves! Of what consequence are you anymore? I... I-I am more than pony, more than life! I am a god! And now, I take my place among the stars." 

Context: Parchment has been revealed to be the killer, and following a big fight, which he lost, he's gone full tilt, unhinged and crazed, having been driven insane by dark magic.
