'Sister'

9 months had passed since the last part. The Summer Sun Celebration was the next day and Celestia was not ready. One filly was taking up her time...
"Sister. You must start your duties."
"Luna, I can't. My daughter needs me. I was like this when you were a filly, when Mum and Dad disappeared..."
"Okay but..."
"But... but what Sister?"
"Twilight requests that you visit ponyville for the Summer Sun Celebration."
"WHAT? When is it?"
"Tomorrow. I have been telling you this."
"I better get ready."
"You don't have to yet. I could take care of Sunlight, if you want."
"That would be lovely, Luna."
