“How did this go so wrong so fast?” Celestia questioned herself. Her answer came in the form of a freaky ball like creature attempting to munch on her face while she repeatedly punched it in its smooth white surface.

“Well, this turned out to be a terrible picnic, now didn’t it?” the Fourth Doctor said. “I say, I was hoping my brain would be a better host to have a spot of tea in, but apparently I was mistaken.”

Celestia threw off the ball creature, but four more quickly took its place. “Doctor, I could use some help here! Do something!”

The Fourth Doctor flipped his impractically long and multi-colored scarf—which looked as if it took over an entire clothing factory’s worth of wool to produce—over his frock coat. Just as he took a step towards her, he ducked as more of his immune system supporters whisked over his head, causing his already unruly mess of curly hairs atop his head to become even more disheveled. “Well, what do you plan for me to do? I can’t really fight myself, now can I?”

With a growl, Celestia headbutted the nearest white orb with her horn, which resulted in a successful defeat as it popped like a balloon. Spinning her head around, Celestia continued popping white orbs left and right, reducing the Doctor’s immune system to scraps.

“Wait, wait, don’t destroy me! We’re still inside my head!” the Doctor said. He grabbed ahold of Celestia’s necklace and dragged her away, while she in turn struggled against his grip.

“It’s not my fault your body decided to attack me!”

“Well, from your behavior thus far, I’m not surprised.”

The Doctor pulled her away from the remaining immune system defenders in the red corridors of his brain, and soon the two managed to escape. Their settings were now a serious of nervous system branches that resembled crystals in a reflective area of the Doctor’s brain.

“Why did I agree to come into your brain for our date?” Celestia asked, more to herself than the Doctor.

“Because you wanted to be marveled by the sophisticated advancement of Gallifreyan brain?” the Doctor said. His endearing smirk sprouted like a blooming flower on his face once again, its most prominent feature being his teeth which could definitely use a spot of brushing. “Or perhaps it was the promise of tea and finger sandwiches?”

Celestia pouted, her muzzle becoming scrunched. “Neither of which I received.”

“Then might you be interested in a jelly baby?” the Doctor asked, presenting a hand full of multi-colored candies in the form of tiny human babies to Celestia.

Arching a brow, Celestia reached down and popped one of the candies in her mouth. Munching on it for several seconds, she blinked. “Wait, these are jelly beans.”

“But in the shape of babies. Isn’t it grand?” The Doctor withdrew another handful from his pocket that seemed to have no end and chewed on the entire lot.

“But then why shape them like babies?”

“I presume it’s because of the human psyche having an uncontrollable urge to consume their young, so they substitute it in the form of candies instead.” Swallowing, the Doctor shrugged. “Or it could be a clever marketing scheme to sell candies.”

Celestia’s left eye twitched, but she finally released an exuberate sigh from her lips. “Okay, I think I’ve had enough of this. Your callous behavior, dark humor, your brooding—which, I might add, is worse than Luna’s, which in itself is quite an achievement—and most of all, your smile! By the gods, your smile!” Celestia shivered just at their mention. “I will personally pay for all the mouthwash and toothpaste you’ll ever need for the rest of your life. Just… please, brush and floss. Please!”

The Doctor put his hands behind his back and kicked at the ground, which was actually a branch of his thought process receptor. “Well, I suppose it would eventually end like this.”

“Well, I’m glad we at least agreed on that—”

“You’re much too prissy and proper for someone like me,” the Doctor interrupted. He held a finger up and tapped it in the air, nodding to himself. “Yes, yes, much too princessy for my likings. I’m more of a ‘free-spirit’ type of immortal adventurer.”

Celestia opened her mouth, thought better of it, and then closed it. “You know what, forget about it. Just get us out of here.”

“Well, we’ll need to exit through the tear duct to accomplish that.” The Doctor hummed under his breath. “And quickly, too. We only have around two more minutes before our clones expire.”

Celestia’s jaw dropped. “Clones? I thought you just shrunk us to get in here!”

“Well, yes, clones. The original you fainted from the process. How do you suppose I got in my own brain in the first place?”

Celestia didn’t even open her mouth this time. She just repeatedly slammed her head against one of the Doctor’s neurol processors.

The Doctor winced just as a light passed through the branch of his brain Celestia was slamming her head against. “Oh, wait, you might want to cease doing that. I think you inadvertently caused my unconscious body to punch someone.”

“...I was laying right next to you on the operating table, wasn’t I?”

“Excellent observation!” the Doctor said, smiling his trademark grin that continued to give Celestia chills up her spine. “How’d you know that?”

Celestia rolled her eyes. “Intuition from too much experience.”
