Twilight looks back on her life- with her coronation just around the corner. With her Future unbeknownst to the knowledgeable mare, she turns to Zecora for wisdom. One Potion later- and Twilight gets to see what she missed out on all of her life.....
Octavia struggles with her life in a time of complacency and settlement happening left and right. She struggles with self identity and true worth, and comes to understand that good friends can help anyone through a dark and confusing time.
This Hearts and Hooves Day, Twilight is alone. Not a big shocker, but it helps her realize something. That without her friends- she really hasn't grown anymore as a mare than that of a filly... That's where (or 'when') the Doctor comes in to help.
