One day at the royal palace Celestia was eating breakfast.
"Good morning, sister." Luna smiles as she walks in.
"Hey, Lulu." Celestia replies.
"Please don't call me that Tia." Luna says.
"Well, don't call me Tia then." Celestia shrugs.
"B-but..." Luna whimpers.
"No buts, I won't call you Lulu if you don't call me Tia." Celestia speaks as if declaring a new law.
"Fine then moon hater." Luna growls.
"Hey!" Celestia gasps.
"Well, I needed to think of a new nickname for you, didn't I?" Luna shrugs nonchalantly.
"W-well then!" Celestia stutters. "Deathbringer suits you just fine!"
"Hey, I heard that." A voice yells from another universe. (Guess who!)
"I have never killed anybody in my life!" Luna cries.
"All right then, I guess Nightmare Moon suits you better then, hm?" Celestia states calmly.
"I-I..." Luna feels tears prick at her eyes and runs to her room.
"Luna!" Celestia calls. Best to give her some space...
Three hours later,
Luna has still not come out of her room. Celestia now concerned walks to Luna's room and opens the door.
"Take me back, just take me back." Luna is staring at her cutie mark, the moon.
"Please don't go back there." Celestia cries.
"Why not?" Luna turns around. "Nobody here loves me." Pointed glare at Celestia.
"I'm sorry." Celestia sighs. "I'm went too far with the Nightmare Moon comment."
"You really mean it?" Luna asks.
"Yes, call me Tia any time." Celestia says.
"And you can call me Lulu." Luna responds.
"Sisters?" Celestia asks.
"Sisters." Luna responds.
