Present Day
But I wake up thinking it's all a dream, but I looked next to me and seen The Doctor. He wasn't normal but discorded. I truly thought that was a dream but I guess not. So I get up and walk to the hallway, It was a little hard to walk because I just woke up but I managed to achieve it.
"Cathy!" Luna shouted "You're up, I thought you and The Doctor were sleeping knowing what you to did to save us."
"What are you talking about?" I ask.
"What am I talking about! Cathy you and The Doctor saved all of Equestria yesterday!" She shouted a bit louder this time.
"Yeah, You saved us from Harmony! We thought we all were going to die from her!" Derpy said.
"Guys,I seriously don't know what you are talking about." I say.
"Derpy, I need to go get 'Tia, Can you go get The Doctor?" Luna says and dashes off to go get her elder sister.
"Okay Luna, Cathy come with me to go get your husband up!" Derpy says as she trots into my room.
"My, Husband?" I say questioning that statement.
"Oh, sorry I forgot that you lost you memories there for a moment, Silly me!" She said "Come on help me, He's a pain to get up in the morning."
Derpy tried to get him up but couldn't manage to get him up.
"See what I mean, Hey you try to get him up he's your husband and all." She said as she nudged me toward the bed.
I poked his face with my right hoof but he didn't budge, As I was going to poke him again Luna came into the room.
"Did you get him up yet?" Luna said as she flew over to where me and Derpy were standing
She landed on him and he finally woke up
"Why did you do that!" He said "You know I have fragile bones Luna, And that's the third time this week!"
"Sorry Doctor." She said getting up and going over to Princess Celestia.
"Doctor, We need your help." Celestia said
"What for?" He asked
"It's Cathy..." She said as she sighed
"Oh no, What's wrong?" He asked
"Well Cathy walked out into the hallway about 10 minutes ago, And talked to me and Derpy and she said that she doesn't remember anything about her..." Luna said
"Cathy, Is this all true?" He said looking at me
I nodded
"Cathy, I'm sorry I can't help you, I'm so sorry. I can't do that kind of thing, so I can't restore your memories" He said as a couple of tears rolled down his cheeks
"Doctor, It's okay I understand" I said as I wrap my wings around him
"No, It's not fine. We need to get them back and I know just the pony!" He said as he gently pushed my wings away and stood up and he turned toward me "Come, Follow me"
"Um, Okay..." I said as I got up following him to the door
I meet him in front of Canterlot in this strange blue box
"Where are we going?" I ask
"To Ponyville! Come on it's not going to hurt you. You've came with me before and you were fine" He said as I stare into the box looking very confused sticking my head inside
"It's bigger on the inside..." I say
"Yep, that's what they usually say" He said as he walked up to this control panel looking thing
"Wait!" Luna shouted as she ran toward us "Doctor, Can I come with?"
"Sure, But just get Cathy in here please"
"Okay Doctor" She said as she grabbed my hoof and pulled me inside shutting the door behind us
:The Doctor pulled this lever and shouted "Allons-y!"
A little bit after that we arrived in Ponyville in front of this library with an owl inside the window.
"Well, We're here." He said stepping out of the TARDIS "Well let's go talk to Twilight"
Luna went up and knocked on the door and this violet colored unicorn stepped up to it
"Well hello there Luna, What are you guys doing here so early in the morning?" She asked
"Well Twilight, We came because Cathy needs a bit of help" The Doctor said
"What for?"
"Well, All of her memories just vanished for a reason we don't know what for" He said
"I know I've seen this somewhere before, Wait here let me go get this book from upstairs" Twilight said and she ran up the stairs almost tripping on the last step "Sweet Celestia, I keep forgetting that last one is taller that the rest!"
She came back down a couple minutes later with a book that reads "Memories, And What They Are For" on the cover
"I read this book earlier and it seems as if somepony cast a spell on her and all of her memories just went away, But there i a spell that can fix it, It's complicated but I know I can do it" Twilight said
"How complicated is it?" The Doctor asks
"Not very, But it's enough to get me confused for a minute, But i also figured it out"
"Well what are you waiting for! Go ahead and do it already, We do have royal duties back in Canterlot we need to take care of"Luna said as she pushed me toward Twilight
"Well, Here goes nothing I guess" She said
Her horn illuminated a magenta glow colored glow and I closed my eyes as the glow started to surround me. I couldn't hear anything but a few muffled sounds and this weird sparkly sound that filled my ears. It was all over within a few minutes but the sound of sparkles hurt my ears, And got this huge headache, It didn't bother me at all. I was so happy that i was normal again and I could be with everypony I love.
"Cathy?" The Doctor asks
"Yes?" I say
"Your back to normal right..."
I nodded my head "I'm my old self again Doctor!"
He came over and hugged me tightly "I missed you Cathy"
"I missed you too Doctor, I missed you too..."
