I kinda forgot to post this but here it is!

The next morning, Celestia was left alone with Twilight since everypony had things to do.
"So, Twilight, where is Spike? I recall my advisor telling me that Spike got you out of the books'', asked Celestia. Twilight looked at Celestia confused.
"Spike...spike? The dragon? I don't know", regretfully answered Twilight. Celestia realized Twilight didn't remember almost anything before the explosion. Celestia decided to use some techniques to help Twilight recover her memories.
"Twilight, do you want me to help you recover your memories?", asked Celestia. Twilight nodded a little too hard. Celestia laughed. She decided to bring the journal that Twilight and her friends wrote in about the friendship lessons they had learned.
"Looks like the bookmarks Discord left from Tirek's attack are still here...now let's see...let's start with Pinkie Pie..", read Celestia. Twilight kept laughing through it all and asked for more. Celestia continued.
"Ow! I think...I think I am getting another memory!", Twilight said after a long while and closed her eyes. She saw herself taking a book from her library and opening it to a page with a picture of potions and magic, a spell it seemed, but she opened her eyes before knowing what spell.
"Twilight! Are you alright?", asked Celestia, very worried. Twilight had fallen to her side and had hit her head.
"Princess, I saw the memory! I took out a book and turned to a page with a picture of a small potion and magic, it was very peculiar", explained Twilight. Celestia thought while she picked up Twilight with her magic. She excused herself for a moment and ran to the castle library, which was destroyed. She decided to have a quick look around and try to find a book open to the page Twilight had mentioned. After just a few minutes of searching, Celestia threw in the towel. It was a big mess and would take lots of time, time that Celestia didn't have due to having to take care of Twilight. She returned to Twilight's room and saw Twilight trying to pick up a quill just as the day before. Twilight struggled but finally picked up the quill and made it come towards her.
"Did you see that! I picked the quill up! I did it!", shouted Twilight from excitement. Celestia congratulated Twilight. She continued reading the journal until it was time to set the sun. She walked towards a window and proceeded to lower the sun as the night before and many more.
"Princess?", asked Twilight.
"Just call me Celestia, what is it?", asked Celestia.
"Well...what's with Fluttershy and Discord, they seem close but from the story you and the girls told me, he once reigned with chaos and betrayed us. Why is she with him?", asked Twilight.
"Well, after the 2nd time Discord was turned to stone, I thought about his chaotic powers, and how it would be a great help for us if he learned to control those powers. I enlisted you all to reform him but put Fluttershy in charge. It paid off. ", nervously explained Celestia.
"Oh, but I woke up during the night and witnessed Fluttershy check on me, I didn't want to cause trouble so I pretended to be asleep and Discord came in and asked if she was ready to do something they had talked about last night, but she refused, insisting that she wasn't ready, eventually, they both left", admitted Twilight.
"Sorry about those two, they have a few problems to be resolved", apologized Celestia. She returned to Twilight's bedside and continued reading the journal till Twilight was fast asleep. Celestia left the room for bed. Celestia got a new book for herself, and read the title, "'Journal of Twilight; Trail and Errors'". She turned the first page to the journal and read some disturbing words. The journal had words written such as "useless, hated, worst pupil, disappointment" and more words alike on the first page, accompanied by what seemed to be teardrops. Celestia gasped and quickly closed the journal. She decided to visit Luna once more. This time, after learning her lesson of flying the night before, she teleported to the castle. She appeared in her throne room with Luna sleeping in a sitting position on her throne.
"Luna...I need to talk to you", Celestia whispered.
"Mm...five more minutes, Mother", Luna said while turning the other way.
"Luna, I need your help", Celestia whispered louder.
"Huh? What? Who's there?", Luna asked after waking up. Celestia laughed, "I guess my duties for today were still tiring even if they were small and easy?". Luna rolled her still very tired eyes.
"Are you here to take your duties back? This is getting tiring", whined Luna.
"Well, as luck has it, my duties are in Ponyville, but I have a question about Twilight", nervously mentioned Celestia. Celestia explained the whole situation and Twilights sudden memory bursts, ending with what she saw in the journal.
"That is concerning...but now that you mention it, I remember a week ago, Twilight had a nightmare that included you, me, and Princess Cadence. I tried to stop it, but Twilight insisted she could do it, at the moment I got another pony having a nightmare, so I left her...I don't know what the nightmare was about though", Luna recalled.
"Is there a type of spell which can help you look back into the dream, fully?", asked Celestia.
"There is actually, but it requires too much power, I would need your help, but I must warn, it takes all our energy combined", warned Luna. Celestia thought it over and nodded firmly.
"Let's try it tomorrow night, I am exhausted!", Luna dramatically groaned. Celestia headed to her chambers and called it a night.

I don't know what to write...i hope you enjoyed!
