I have a theory how Nightmare Star would appear in the season finale. After knowing of Nightmare Moon's return, Princess Celestia had planned about what should be done. She can absorb the dark energy out of Nightmare Moon, bringing Princess Luna back. But there was an alternate plan. She knew the pony with the cutie mark on the Tree of Harmony will be the next princess, and wield the elements. But because of Starlight Glimmer preventing the Sonic Rainboom, she just never came. So when Nightmare Moon came; Celestia absorbed her dark energy, revert her back to Princess Luna, and transformed into the wicked Nightmare Star.
