As Nightmare Night drew closer, Luna was finishing preparing for visit to Ponyville. The night princess had asked her niece, Princess Cadence, to look after Nebula, Star Shower and, Aurora for few hours. The Princess of Love happily agreed to watch the fillies. In the meantime, Luna still could not shake the feeling that her family was incomplete. The best she could do was to talk with Celestia about the ordeal. Unfortunately, Celestia wasn't able help in this situation. All Celestia could suggest was to write a letter to Twilight Sparkle for a second opinion.
"Sorry I can't be more help." Said Celestia somewhat downtrodden.
"It's okay sister. You just being a listening ear is more than helpful." replied the night princess giving her sister a loving nuzzle.
As Luna walked back to her chambers to send Twilight that letter, she spotted a mother and her colt heading towards the thrown room. Something clicked inside the midnight blue princess's mind at the sight. The reason why Luna's family felt incomplete, was because she wanted a son. Luna continued to her room with renewed vigor, now that she knows why the feeling of wanting foals never fully left her. The only question remaining was, who was going to be her son? She did consider her nephew, Prince Blueblood, but ultimately rejected the idea. By the time she reached her room, Luna had decided to go with the young earth pony colt Pipsqueak. Luna remembered meeting the colt back in Ponyville, when she first wanted to reconnect with Equestria during that year's Nightmare Night. He had struck the princess, as a honest and trusting soul. Especially, when he had sent a letter with picture to her for a class assignment.
"Soon, my little ones. You'll have a little brother to play with" Said Luna softly to her daughters as to not wake them.
Luna slowly went to sleep, excited at prospect for having a son. All aspects of sending a letter have left her mind.
