That night, as she got ready for bed, Sunset couldn't help but remember the time she took some time to go visit her mother a month after becoming Twilight's surrogate big siser.

"But of course, it's a day I'll never forget..." Sunset said to herself.

One Month after Sunset met Twilight...

"Your going to go do what now?" Twilight asked her surrogate big sister.

"Well now that midterms are over, I wanted to take some time to check up on my mother back home. See how she's doing." Sunset told her surrogate little sister. "But I'll be back by the time the next semester starts up okay? You just be good and practice that magic of yours while I'm gone. I'd love for you to join me in Princess Celestia's School as soon as your of age to do so." Sunset said.

"The Summer Sun Celebration is happening while your gone Sunset. We were thinking of taking our daughter to the event." Twilight Velvet said.

"That's a great idea, you'll get to see Princess Celestia in person that way." Sunset said. She then went to grab her things and started leaving for the train, only to find her teacher there.

"You are worried about your mother, I could tell the moment you requested to go back to your village." Princess Celestia said.

"Yeah. Surely by now, word of my brother's disappearance has reached her." Sunset said. "...No one has found any clues yet though?" Sunset said.

"The royal guard keeps hitting dead ends, and admittedly, so am I. If only there was SOME clue he left behind." Princess Celestia said.

"Knowing my brother, he probably doesn't have some note saying 'go here if I don't think I can pass midterms' anywhere." Sunset said.

"It would make things easier if he did so." Princess Celestia said. Sunset giggled.

"Well I better go. I'll see you in two weeks Princess." Sunset said and left on the train.

Present Day...

"I had no idea what state my mother was in at that time...and once I knew...I had to do SOMETHING..." Sunset said.

The Past...

Sunset arrived at her home. "Mom, I'm home for two weeks." Sunset called out. She searched her home and found her mom, but she was very malnourished. "Oh no...MOM!" Sunset said.

Over the course of a few days, Sunset did her best to force feed her mom some food and even sent an emergency letter to her teacher explaining the situation. By the time the first week ended, the royal guard was there to take Sunset and her mother back to canterlot, where Sunset's mother was given more food to help bring the mare up to normal nurishment levels.

"It seems you were right to be worried about her." Princess Celestia said. "By the way, it seems you've made an impression on Twilight: She wants to join my school." She added.

"I have no objections, Princess. In fact, I hope she becomes your second student." Sunset said.

"This is a welcome surprise by you. You’re not afraid of her upstaging you?" Princess Celestia asked.

"Twilight has more magic then I could ever muster. I can sense it in her. I'm fine with her becoming your student alongside me. Plus, I'd get to spend a lot more time with Twilight that way." Sunset said.

"Your a strange one, Sunset Shimmer. But then again, your family is a bit strange: Your mother seems to have starved herself to this length because your brother went missing. And I don't need to remind you of that." Princess Celestia said.

"I have to find him; now more then ever." Sunset said. "I promise I will find him Princess; if not for me, then for my mother." Sunset said.

"I see. Then for the time being, I will move your mother to Canterlot. It'd be best for me to keep an eye on her, just so this won't happen again." Celestia said.

"Thank you Princess." Sunset said.

Present Day...

As Sunset hopped into bed, she silently reaffirmed her promise: She would find her brother, one way or another. If not for herself, it'd be for both her mother, and for the pony her brother referred to as "Glim-Glam" who Sunset has found out, is named Starlight Glimmer.

Author's Note

It's another Flashback Chapter! In this one, as you can see, Sunset flashes us back to the time when she had to force feed her own mother because the poor mare had starved herself and became malnourished as a result. As such, we see a dynamic between Sunset and Princess Celestia that I feel like we got jipped on in the original timeline.
