Starlight walked into the library just behind Twilight and Spike. "Wow, there are a lot of books. We're going to dust them all?" The unicorn asked.

"Yeah, Twilight has me do this pretty much all the time." Spike replied mildly. "Well, we best get to it.

"Oh my gosh!" The princess gasped, taking the logos and flipping through the pages.

"What are you even doing with a logos?" Starlight asked.

"I'll explain when back, Spike!" The Dragon popped his head around another corner and saw the glow.

Twilight ran through the portal and started talking. "I'm so sorry I didn't get here earlier. I didn't get your message until just now because I was stuck in this time travel loop, and you know, it was the strangest thing that ever happened to me." She then took note of Sci-Twi. "Make that the second strangest."
