Shortly after the Grand Galloping Gala, Aita is on his way home from the CMC clubhouse when Lightning Dust engages in a conversation with him. Unfortunately, after Aita tells his friends, Lightning Dust gets a U-Fly letter about a rental chariot that not only postpones her welcome party, but, once found out, also ends up getting Discord framed. To get everything figured out, Aita will have to put his deductive skills to the test with the help of Fluttershy and Lightning Dust.
