If their recent discovery wasn’t enough, Flurry rushed to see what Starlight’s most recent memory was… And when she saw her friend getting shot down from the sky, she knew she had to move quickly. “Princess Luna–” She didn’t have time to explain before Luna picked her up, holding her close as they both raised into the air.
“Little star, you know where to go and what to do now. You will awaken, and you will rush to Ponyville and stop her, understood?”
Flurry Heart paused for a moment, but nodded quickly. “I’ll try my best!”

Flurry Heart woke up with a gasp, looking up to see her Aunt watching over her. She spoke quickly, too panicked to remember to slow down. “Aunt Twi! I-I saw Luna- and I saw Starlight’s memories and she had the Alicorn Amulet and I gotta go!”
“Slow down, Flurry Heart.” Twilight put her hoof on her shoulder. “If you think you are going alone, you are sorely mistaken. You passed out trying to find a solution after all, and if what you say is true, then I have a friend to save.”
“We BOTH have a friend to save!” Flurry spoke up. “She’s in Ponyville fighting Luster and Sunset and- I saw Luster get knocked down!”
“Then we both must go immediately. Come with me!”

So, both of them flew off.
