After Celestia is busy training Twilight and doing her "royal duties," she begins to fade out of Luna's life as she did a thousand years ago. Luna's jealousy gets the best of her as she runs away from the castle, in search of a powerful source to overthrow her sister. Along the way Discord finds her and eases her nerves slowly, not noticing the big impact he has on her life. He begins to fall for her but realizes she would never feel the same way. After all, they are both over a 1000 years old and Luna still looks young as a newly planted flower, but Discord himself has changed to look older, though he is immortal like her. Discords discouragement gets the best of him as he slowly backs away from Lunas life, and her jealousy grows once more. (The story is NOT about the past. It's about the present, notice Princess Twilight mentioned in this description)
