Ditzy reentered the shelter.
"Doctor, I can do it. I may be scared, but I can do it!" said Ditzy. River scowled.
"Enough chitchat! Is the filly in or out?" asked River. The Doctor grimaced, and looked at his companion. Such a beauty she is, with her mane flying about like strands of sunshine. He wouldn't lose her. He wouldn't lose another companion. Not in this universe. Ditzy nodded.
"Yes. I'll do it." said Ditzy. The Doctor grabbed Ditzy's hoof and looked into her eyes.
"Ditzy, you can't, that creature has the power of a god. It will kill you." said the Doctor. Ditzy narrowed her eyes and slapped the Doctor's hoof away.
"Listen here, Doctor. I take it upon myself to protect Equestria, no matter the cause. Now what if I can change history? What if I help the Princesses defeat Discord? But what if none of that ever happens because YOU were too selfish to let me go?!" Ditzy shouted. The Doctor met her head on.
"I'm not being selfish, I'm trying to protect you!" said the Doctor.
"You want to protect me? Let me go. Don't let me wallow in the guilt that I did nothing to aid in the defeat of this tyrant. You may have a machine that can dances across time and the stars like a pegasus dances across the clouds, but you cannot control everything in this universe, Doctor." said Ditzy, pulling away from the Doctor. Ditzy walked up to River, looking her in the eye.
"Where do I start?" asked Ditzy. River smirked and the Doctor exited the shelter. He sat in the grass, staring at the sky. The Doctor smiled. Ditzy Doo. She may not be human, but she's exactly like all the other companions who came before her. The Doctor closed his eyes, remembering all the past companions he had. Rose, Martha, Donna, Amy...all of them lost to him. He could not let Ditzy vanish like that. He could not let her go. The Doctor frowned.
"You. Stop the act. I know you're here, I sense you." said the Doctor. There was a soft chuckle.
"Very good, Time Lord." said Discord as he materialized from thin air, clapping slowly. The Doctor stood up.
"How do you know what I am?" asked the Doctor. Discord merely laughed and examined his talons.
"I'm capable of many things, Doctor." said Discord.
"You don't know me." the Doctor growled. Discord frowned.
"Oh but I do, 'Mr. Spock'. You are just a lonely creature, the last of your kind, running away from your past in a small blue box. The pitiful universe you resided yourself in burned, there is nothing left of the race you did love so much, the 'humans'. But being the hitchhiker of the cosmos you found yourself here, even found a little mare to replace the companions you've lost. But you will abandon her, you will leave her all alone in the dead silence of space to save her from the ghosts that will never stop chasing you, always asking you one question...Doctor who?" said Discord. The Doctor covered his head.
"Y-You're taking my memories...you're digging your way through my very thoughts..." said the Doctor. Discord laughed.
"Ah yes, you catch on quick, Time Lord. Oh, what's this? A plan to apprehend me? Oh, dear, you already plan to throw the cross eyed pegasus into danger for your own good?" said Discord. The Doctor charged at Discord, only to be stopped by a magical barrier.
"If you even do so much as SCRATCH her I will kill you." the Doctor growled. Discord outstretched a talon and lightly touched the Doctor's forehead,
"What are you doing? Is this how you plan to kill me?" asked the Doctor. Discord held his talon in place.
"No...I'll leave the killing to you." said Discord, withdrawing his talon. There was a bolt of electricity, and the Doctor's eyes glazed over. He collapsed on the ground to the sound of Discord's maniacal laughter.
