As Nightmare Moon disappeared into the castle after the six ponies that came here to stop her, Keith and Lance were worried about their safety. They flew up the stairs and over the bridge into the castle. When they got into the castle they looked all over but could not find anypony then they noticed a bright rainbow light coming from a tower. They went to investigate, hiding at the door frame and found six ponies, two earth ponies, two pegasus, and two unicorns, one being Twilight, that were all wearing strange jewelry. Five wearing necklaces and Twilight wearing a tiara.

"Gee, Twilight! I thought you were just spoutin' a lot of hooey, but I reckon we really do represent the elements of friendship." the orange earth pony said.

"Indeed you do." Princess Celestia's voice suddenly rang out. At this, the sun finally rose and a bright light orb entered the room. Eventually, the orb took the physical form of Celestia herself as the light itself vanished. All six of the ponies bowed upon seeing their ruler take form.

Twilight gave out a gasp as she saw her mentor. "Princess Celestia." Twilight called out as she approached her mentor, happy to see her again, nuzzling against her mentor's neck.

Celestia returned the gesture, then said, "Twilight Sparkle, my faithful student. I knew you could do it."

Twilight was confused at this, "But... you told me it was all an old pony tale."

Celestia politely countered by saying, "I told you that you needed to make some friends, nothing more. I saw the signs of Nightmare Moon's return, and I knew it was you who had the magic inside to defeat her, but you could not unleash it until you let true friendship into your heart. Now if only another will as well. Princess Luna!" At this, Celestia turned her attention to another smaller, blue pony surrounded by several bits of glowing blue armor. This smaller pony, who was apparently Princess Luna, gasped upon seeing her smaller size and how Celestia was walking towards her while towering over her. "It has been a thousand years since I have seen you like this. Time to put our differences behind us. We were meant to rule together, little sister."

"Sister?" Twilight and Rainbow Dash said in confusion, as they never knew Celestia had a younger sister before. Meanwhile, Keith and Lancelot were also confused, seeing as how the only sister they knew about was named Dawn.

"Will you accept my friendship?" Princess Celestia offered her sister this second chance.

Silence fell across the room, as all six of the ponies leaned forward expectantly, hoping that the younger princess would accept. The pink earth pony leaned forward so much that she fell forward. Finally, the younger sister responded, approaching her older sister, "I'm so sorry! I missed you so much, big sister!"

Not wanting to interrupt the touching reunion, Keith and Lance left the castle to inform the guard that Celestia was safe and that they didn't need to storm Ponyville.

Later that day after Keith, Lancelot (Lance wanted to be called this after everything that happened) and the guard got back to Canterlot.

They were waiting for Celestia and Luna. When they walked into the throneroom and saw the two princesses there, Lancelot and Keith ran even if it hurt his hoove to do so into Celestia's hooves. As Celestia hugged Keith, Luna looked at him confused at the new alicorn.

"Aunt Celestia, are you and Aunt Luna ok?" Keith questioned to make sure the two princesses were fine.

"How did you know Luna's name?" Celestia asked, seeing as how no one else had said Luna's name in this conversation yet.

"Uhhh. Read it in a book?" Keith awkwardly answered.

"Lucky guess?" Lancelot awkwardly answered.

Celetia looked at them with a knowing look. "So you know or guess that this is my sister Luna." Celetia explained to the both of them about Nightmare Moon, what happened, and how the day was saved. Luna didn't say anything because she felt very shy and discouraged about what happened.

"So Twilight and Spike are going to stay in Ponyville and Twilight is going to send me letters about her findings and lessons on friendship. I think it would be in your best interest to read them with me." Celestia explained.

"Just what I wanted to do with my time. Learning lessons five year olds learn." Keith sarcastically quipped.

"I know that you have your own misgivings in regards to making friends. However, I think that you would be better off reading these lessons. It would be helpful in getting you ready to make friends again," Celestia calmly responded.

"Ugh, fine! But Lancelot has to be there too." Keith answered as he pointed to Lancelot. "I will not be going through this torture alone."

Celestia was not exactly pleased with this response. However, instead of addressing it, Celestia decided to ignore the bitter quip and said, "It has been a long, exciting and eventful day. I would recommend that we all go get some sleep."

At this, Keith and Lancelot both left the room. After they both left the room, Luna finally spoke, "So, this Keith pony is he related to you?"

Celestia shook her head, "No. He is the great, far off, grandchild of our sister, Dawn. Look, it is pretty late. We should probably get some rest and talk about this more later, Luna."

Luna nods, and they both go off to head for bed.
