Her eyes were cold and she did not speak. Opting to turn her head away and shove a forkful of food gracefully into her mouth.
"Luna"
"I came here to eat, not to reconnect, Celestia"
Silence engulfs them and the tension between them was palpable.
"Sister, please I don't understand what's happening"
Luna closes her eyes and breathes deeply
"How can I tell you Celestia? How can I tell you the truth? That the little sister you love died?"
I dont understand...

Perhaps what it means is, physically Luna's still the same. But mentally, she's a very different pony now.
7744152 Ah, okay.
Makes sense.

But what happened to her?
This story sounds like it has a prequel, one that doesn't exist, one that explains everything. This story acts like we should already know the backstory behind it and yet we don't and never will.
It's nice but an explanation for all this would have made it better.
This seems incomplete. I really hope that you continue this, so we find out what happens.
Writing wise...
When writing, try to match the actions to the pony talking, instead if describing them both at once. It helps keep things more organized, and allows the reader to know who's talking.
Overall, it's a good story. Even if it was slightly confusing.
But Spike... He doesn't exist in this timeline?
