As Sunset began to turn in for the night after the Pinkie Sense incident, Sunset was looking out the window at the night sky. Twilight and Spike were both fast asleep.

"...Brother, wherever you are, I will find you. No matter if your alive or dead, I will find you. For our mother. And then maybe you can finally tell me more about this 'Glim-Glam' you kept mentioning while you were at Celestia's School for Gifted Unicorns with me." Sunset said. "Because now I'm beginning to think, that it wasn't some toy you kept talking about. It had to be an actual Pony. I only wish I hadn't kept telling you to get over a toy. Maybe then you'd still be here." She added said.

Sunset began to think back to a time of one of their many fights over what her brother was calling 'Glim-Glam'.

Three Weeks before Sunset's Brother disappeared

It was one of the weekends when Sunset decided to enter her brother's room, and that's when he heard him say something.

"Oh. It's you sister." Her brother said. "What's up?" He asked.

"What's up with me? What's up with you?! I can't help but be concerned for you when you've been growing further and further away from me." Sunset said.

"Well I never wanted to come here! Not without Glim-Glam!" Her Brother said. Sunset glared at her brother.

"How many times do I need to drill this into your head brother of mine? Get over your silly little toy." Sunset said. "Your a growing pony, you don't need toys anymore." She added.

"And how many times do I need to tell you that Glim-Glam is not a toy! Glim-Glam is my best friend and I want to go back home to see her. Like now!" Her Brother practically snapped at her. Sunset felt her anger reaching a boiling point.

"SUNBURST, YOU KNOW THE RULES HERE!" Sunset said. "And don't make me have to tell mom when I can send letters to her that you were flunking your studies on purpose just because of some toy you forgot to pack!" Sunset said.

"UGH! YOUR NOT LISTENING TO ME!" Sunburst said and suddenly forced his sister out of his room and shut it. Sunburst proceeded to lock his door. "Why...why did my family force me to leave my best friend? I want to see her again...but at the rate things are going...I may never see her again..." Sunburst said as he began to cry. "Glim-glam, if I ever do see you again, I want you to know that I still consider you my best friend in the whole wide world..." He added as the tears fell.

Outside, Sunset heard her brother weep.

"...Geez. All this over a toy." Sunset said.

Present Day...

"The more and more I think about that day when I heard you say 'Glim-Glam, if I ever do see you again, I want you to know that I still consider you my best friend in the whole wide world.' while you cried your eyes out, the more and more I think I'm starting to realize, that I was wrong about what you were calling Glim-Glam or more specifically, who you were calling Glim-Glam." Sunset said. "Well Sunburst, my dear brother, if I do ever come across the one you were calling Glim-Glam, I'll be sure to tell them what I heard you say: You still consider her your best friend in the whole wide world." She added before finally heading to bed. "I only wish you had told me an actual name though." Sunset briefly stated before she fell asleep.
