A Third Gem

     "So, you're telling me it's memory loss?" Twilight asked.

     "No." Rainbow Bolt said.

     "Memory reposition?" Rarity asked.

     "Nope." Apple Butter said.

     "Nightmare Moon?!" Pinkie asked.

     "What? Where?!" Lollipop Swirls dived under one of the library tables.

     "Hold on jus' one little minute." Applejack said, "Did y'all forget to explain why you had those blueprin's in the firs' place?"

     "Oh yeah, that." Leaf said, "Well, there was one artifact in a museum that could have, well, gotten rid of his memories, but we were trying to find out how somepony could have gotten it out and in so fast, and why."

     "No artifact could cut memories so perfectly." Twilight said.

     "There has to be something." Silver Rite pulled a book from the shelf, checked the cover, and opened it.

     "Why can't we get Fluttershy here?" Rainbow Dash asked, "It is HER brother."

     Everypony stared at Rainbow Dash. "What?" she said, "Did I say something."

     "Ah'll go get Fluttershy." Applejack trotted out the door, only to come back minutes later, with a timid mare.

     "Oh, are you having a study session? I'll come back-" Fluttershy started to walk out the door.

     "It's about Cloud." Twilight said, and Fluttershy immediately turned around.
