Celestia sat idly at a dining table, staring off and clasping her hands to her mouth. In front of her, a small pastry sat, awaiting to be consumed. Across from her, Luna sat, quietly eating a small salad, trying to avoid looking back into her sisters eyes. The two sisters had come here a bit after the initial wedding, and for several minutes, Celestia had not done anything, leaving the room in a uncomfortable silence.
Taking a breath, Luna set her fork down and broke the quiet.
"Is something troubling you sister? Perhaps you would like to discuss it?"
Breaking out of her stupor, Celestia met Luna's eyes. For a few seconds, nothing was said, until Celestia let out a sigh.
"Sorry Lulu. I was just thinking about that newcomer."
"Ah. The one who drop-kicked Queen Chrysalis?"
Celestia raised an eyebrow before continuing, "...Yes. I've been wondering about her and what she is capable of."
"Indeed. Not many can get that close to somepony with that kind of magical power and get away with it." Luna mused before focusing back on her sister.
"That's just it, my sister. Autumn, as she calls herself, is strong. She took a blast from queen chrysalis, and merely got the air knocked out of her. If a pony were in her position..." Celestia shuddered slightly at the thought. Luna nodded, motioning her hand for her sister to continue.
"Along with this, the speed in which she travels seems on par with only the best Wonderbolts. Even in my daze in the cocoon, she was able to reach the ceiling, cut me down, and take down several changeling guards before I even touched the floor." Celestia took a breath after the sentence, before eyeing Luna for response. On Luna's part, she had never seen her Celestia this stressed in a while. Even when discord had escaped, Celestia had only been mildly alarmed, and that was during the chaos in ponyville. Considering this, Luna spoke.
"Sister? Are you afraid of her because she's an unknown to you?"
Celestia's eyes widened, before she cast her eyes down in defeat. "Am I that easy to read?"
Luna chuckled a bit, her voice showing a tinge of amusement, "I've only been sisters with you for over a thousand years."
Celestia gave a light laugh, and Luna spoke again in a soft tone, "Sister, do not fret. I believe that 'Autumn' is not a threat to Equestria. In the time we've been aware of her, she charged the changeling queen and saved you from danger." Luna paused for a second, considering her next words, before continuing, "I heard some chatter between the guards. There were two who accompanied Autumn to confront Chrysalis. Perhaps we can ask them to fill us in on how she is like?"
Celestia gave a small smile before nodding. She spoke again, this time in a quieter tone, "Thank you Luna for the reassurance. I'm sure we'll be able to talk with those two guards soon."
Luna waved her hand, "There's no need to thank me. It's what a good sibling does. Now how about you eat your meal." The princess said, gesturing her hand to the lone pastry. Celestia smiled at Luna before picking up her fork, intent on digging in when a small knock rung on the door.
Celestia went to speak when her sister interrupted her, hushing her with a gesture, then speaking herself.
"You may enter."
The door creaked open, and a purple mare, Twilight sparkle, poked her head in. She gave a small wave to Luna, who returned it with a nod, before her eyes landed on Celestia. She cleared her throat before speaking.
"Um- Princess Celestia. Me and my friends are going to be heading to ponyville for a couple days until the wedding is rescheduled. Are we alright to go?"
Celestia gave a nod, speaking, "Of course you can. May I ask why?"
"Well... Pinkie Pie said that Rainbow Dash decided to go with Autumn to help her find her teammates. And knowing Rainbow, it might end in trouble, so we decided that we should probably go try and be there to help if that does happen."
That put the princess in a pause, which was quickly picked up on by her sister. Twilight turned as Luna began to speak.
"Thank you for telling us Twilight. You may go and help your friend."
Twilight, confusion in her mind upon seeing her mentor out of it, stuttered out a response, "T-thank you Princess Luna. We'll be back in a few days." After Twilight retreated from the room, Luna spoke quietly.
"So one of the Element bearers decide to follow the mystery creature to somewhere most likely dangerous. Great." Luna gave a small laugh at the end, which caused Celestia's expression to harden slightly as she spoke.
"This isn't a laughing matter, you know."
Luna turned to her sister, again using her soft tone, "I'm sure Rainbow Dash will be alright. Not only does she have her own strength, her friends will also be there to help."
Celestia gave an uncertain look, before refocusing back on the door. "I hope so..."
