Just another little chapter that happens after the first
Celestia flew in the window and was surprised to find Luna home already.
She looked up from her book and smiled. "Hello. How was your evening?"
The way Luna was looking at her… "You knew! You could have at least warned me!"
"I realized that Twilight Sparkle had feelings for you, yes. And I guessed that she wanted to tell you tonight. You really had no idea?"
"No! I don't think of Twilight like that!"
"So what did you tell her?"
"I just kind of…ran away." She started pacing back and forth. "I probably hurt her feelings. I should go back and talk to her. Or at least write her. Oh, why am I acting like some schoolfilly? ? It's not like this has never happened before!"
Luna stepped in front of her. "'Tia, maybe it's because you feel the same way about her?"
"Luna, it makes no sense! She's my student. She's thousands of years younger than me!" She sighed. "And she'll die thousands of years before me."
"You are always talking about her."
"Well yes, she's a brilliant magician. And of course I admire her. She saved the world twice. And she saved you when I couldn't."
"And she is rather cute, is she not?"
"Well sure. She has a cute smile and a pretty mane, and those big eyes. Purple is my favorite color but… Luna, I know what you're doing. Why are you so interested in this?"
"I just want you to be happy, Sister." Luna cuddled against her. "Just think about how you feel. And don't think too much about the years and the ages and the immortality. You are old compared to everypony. Even me."
Celestia gave her an irritated look and tweaked her tail before they both burst out laughing.
