As she arrived at the library, she found that, curiously, the door was now ajar. Luna rapped the door as she went by, alerting those inside. Inside were Twilight Sparkle and the bouncing pink one known as Pinkie Pie. Luna was interested to find that Twilight looked a bit less stressed than before; she wondered if Pinkie had somehow cheered her up.
“Heeyyyyy! Luna!” Pinkie called. “I was wondering where you might have wound up after the other day, I thought that it was really lame that I didn't even get to say anything to you! I guess I do now, though!”
Luna let out a small sigh, Pinkie Pie was the last pony she wanted to deal with right now. It would seem as though she simply could not spend the time before tomorrow in peace. “Hello, Pinkie... do you have anything useful to say?” She asked.
Pinkie took that as a cue to talk about everything she thought anyone might want to hear, “Well that depends on what you consider useful, I think I have lots of useful stuff to talk about, like how I made these extra yummy cookies the other day, or how Mr. Cake slipped and his face landed in pie, or how Celestia-”
“Now now, Pinkie,” Twilight interjected, “I don't believe Luna wishes to hear about such trivial things; in fact, I think she might want some time alone, you know?”
Luna was curious: it seemed almost as though Twilight hadn't wanted Pinkie to finish what she had been about to say about Celestia. She supposed an explanation for that would be that Twilight simply didn't want Pinkie to speak more about that odd meeting; still, something seemed off to Luna.
Pinkie started up once again, “Why would anyone want time alone? It's always more fun to spend time with other people! I mean-” She was once again silenced by Twilight, this time with a piercing glare. “Okie dokie, I guess maybe I should go!” she said, taking the hint.
“So Twilight, I take it you are feeling better than before?” Luna asked, still feeling curious.
“Oh, well, yes; I've realized that sometimes it's best not to worry too much about things,” Twilight said, “It's not something that comes easy to me to notice, but I'm thinking maybe I've been overreacting.”
“Truly? That is good to hear, although it seems a bit sudden...” Luna said, walking over to a bookshelf, “In any case, would you mind if I stayed here for a bit and read?”
“I don't see any reason that wouldn't be okay,” Twilight replied, “I actually need to go out and check on the preparations anyways. It's a bit late for it, but I can't let yesterday cause the Celebration to have any problems.”
“Oh, alright then,” Luna said, her voice contained a bit of suspicion. Even though Luna didn't know Twilight very well, it still seemed unlikely that she would be so very upset, and in just a couple of hours be completely fine. There was also something else that seemed a bit off, like she was holding a secret or something. There wasn't an explanation Luna could easily think of; she wondered if perhaps there could be some sort of thing going around, a disease perhaps, causing ponies to act in uncharacteristic ways.
“If I don't come back before it, I'll see you at dawn in the town square,” Twilight said, leaving. Luna considered whether she actually wished to go; Celestia would be there, and the thought of seeing her made Luna's stomach bubble with anxiety. Hiding from her sister wouldn't be any good though, and might even make her become more harsh when they do finally meet.
She stood for a moment, considering things, but then the question of what was going on with Twilight came to her mind. She was acting odd, and perhaps there was a good reason for it. She thought of following her; if the feeling Luna had that she was holding a secret was true, it might reveal something about Celestia as well.
