This story is a sequel to I Loved You
A while after the Grand Galloping Gala, Moondancer was invited to attend the royal wedding of Princess Mi Amore Cadenza and Shining Armor. However, the wedding turned into an invasion as Changelings attacked everyone. The resulting battle left her comatose. This story briefly follows up on her time spent comatose.
This takes place after I Loved You and has at least a few trigger warnings: pulling the plug, an introspective of what happens when someone dies, realism in a show full of pastel colored horses, and a little bit of Canterlot Wedding Consequences. That said, do keep in mind that this is tagged as "sad" and not outright "tragedy".
