We have instances where Luna has her normal, softer voice and it's obvious she's still the sweet and kind Luna we got a glimpse of in the series pilot, she's just confused and behind the times, which is perfectly understandable given her situation. If I were gone from society for a thousand years, when I returned I would need more than a year to sort it all out. Plus, while she was exposed to Celestia's influence, that doesn't mean she had much to do with the
hoi polloi during that time. If anything, she reminds me of Twilight Sparkle when we first met her; that being totally unprepared to interact socially with others.
She did know about Nightmare Night (lending to the idea she studied the history of it), so she's aware that things have changed. I just think she didn't realize
how much things had changed. Like Twilight, she's probably a bookworm, or at the very least rather studious, and so she absorbed as much as she could learn in her year of adjustment, but that doesn't make one ready for society, which is a totally different animal and can blindside you no matter how much you've tried to adjust.
I think we'll see more normal Luna in the future (I hope to see lots of Luna in the coming episodes ahead). I can't wait either way. I <3 Luna.
