Twilight completely confuses her friends near the end of the story by answering all 22 of their questions from memory before they could ask. Some of them are easy to figure out, but some of the later ones get into Noodle Implements territory.
Twilight: A time loop, three hours, whenever I die, changelings, Chrysalis, I think about a month, somewhere around a hundred, yes, yes, no, 5:57, all of them, yes even the squirrels, Spikeís fine, no just me, you donít want to know, the Elements of Harmony, I donít know, yes, no, yes, and three tea kettles.
The newly ponified Butterscotch somehow manages to bond with Twilight over the fact she had probably beaten him to death with a baseball bat in alternate timelines. Also, apparently potatoes taste like hubris.
During the final chapter, Celestia asks Twilight for some assistance. When she agrees, Celestia levitates over a stack of menial form and paperwork roughly twice as tall as Twilight. Her response in the narration?
Twilight: I love her so much sometimes, I don't even know how to properly express it.
Twilight discovers that she has been outed to the entire town by a parrot that Fluttershy was petsitting.
