Twilight Sparkle felt terrible for the way she had treated her old friends in Canterlot.
"For a supposed 'Princess of Friendship,' I haven't been a very good friend. I should do something to make it up to them."
She took the next train to Canterlot and smashed Minuette, Lemon Hearts, Twinkleshine, and Moondancer.
Then she returned to Ponyville and smashed Lyra Heartstrings.
Twilight Sparkle felt a little better.
Staryak Glimmer stealthily eavesdropped on Princess Twilight while hiding behind a restaurant menu. Then she quietly smashed her table and subtly demolished the restaurant. By the time anypony noticed what had happened around them, she had disappeared into the shadows.
