''What's with the traumatized faces ? Have you seen a ghost ? Do I have something on my cheek ?'' asked the glass-wearing Pinkie Pie.
''Pinkie Pie ? Is that you ? So you are okay !'' shouted Rainbow Dash. She suddenly jumped on Pinkie Pie, hugging her vigorously.
''We were so worried about you !'' said Twilight, leading the others into a big group hug.
''Girls, I don't think that's actually the true complete Pinkie Pie.'' explained Princess Luna calmly.
''WHAT !?'' asked the others, backing up from the hug.
''Well, she is right.'' said the pink pony.'' I'm surprised any of you failed to notice that unlike the outside Pinkie Pie, I wear glasses.''
''Well, I guess we got a bit ... ahem ... Carried away.'' said Rarity while blushing. ''Anyway who are you then ?''
''I am Pinkie Pie's Conscience, though my full name is a formality. Just call me Conscience, that should be more adequate.''
''Conscience, nice to meet you. Could you please tell us where we are ?'' asked Twilight.
''You're in the Hall of the Brain, also called Antechamber. This is the first and most, well ''exterior'' part of the brain, so to speak. You have basically arrived at the beginning of the brain, in the Prefrontal Cortex. I supervise the Jugdement capabilities of Pinkie Pie, but I'll explain that further on. Is it all clear for now ?''
The baffled looks on everybody's faces should have been a clear sign of how everything was absolutely not clear. Princess Luna was stupified too, but she was the only one that actually didn't gave that impression.
''Well, why don't you follow me ? I still have to understand what you are doing inside this silent place. Oh, now that I talked about it.''
Conscience clapped her hooves to suddenly make some chillout/lounge music appear. The soft tunes of the music suddenly made that light green-ish room appear more vibrant and alive, making anyone also feel much more comfortable, actually.
''Much better, you know, it's one of our main rules here, any thought in this brain shall not work without any musical accompaniment, we try to fight boredom anyway we can. So, we can go now ? A few steps may help us a lot.'' said Conscience to the group, after they suddenly snapped out of their surprise and marvel.
''So, what exactly is your job here Conscience ?'' asked Twilight.
''Well, basically I control every single idea that is trying to make its way into the brain. I let the good ones in, and I also dispatch of the bad ones. You see that garbage can over there ?'' said Conscience indicating a big green garbage can. ''That's where I throw away the bad ideas, even though I never understood where they go after.''
''Well this pony's doing one heck of a job then, considering Pinkie's behaviour.'' thought Applejack sarcastically.
''But enough about me, what are you doing here ? I mean, you're not supposed to be hosts of a brain.'' asked Conscience.
'''So, it's kind of a long story : basically the outside world Pinkie Pie has went crazy and she's not acting like her normal self. In fact she seems completely paranoic and afraid of everyhting and everyone to the point that she tried to hit us with a frying pan and she refuses to make contact with us or accept something from us. So we are here to help her by discovering the reason why she's acting so strangely. '' answered Twilight.
''Strange enough, these definitely sound like bad ideas, even though I never saw them here, as in they never arrived. Considering the way you are describing the situation, it seems more like an excessive amount of fear. I would also consider a neurosis, but that happens rarely, and never on such a serious scale. You see, the difference is that neurosis are created when ideas arrive for a huge removal or repression of impulses and desires, or when the brain fails to create an individual response to a general problem. It's usually an inconscient well, ''conflict'', that we try to satisfy anyway in order to avoid a crisis on a bigger scale. We basically find a compromise. Fear on the other hand, is a response to a situation of danger. The main leader thoughts that control the various feelings then find a way to confront fear together. An excessive amount of fear must be the result of a failed control by the feelings. You should probably talk to them about this fact, I'll guide you to them.'' said Conscience after the long explanation.
''That would be great, thank you, but aren't you supposed to stay on guard here ?'' asked Princess Luna.
''Oh, don't worry, I have someone that can cover me.'' answered Conscience. ''Common Sense, could you please come here ?''
After a few moments of silence accompanied by the still going lounge music, another Pinkie Pie entered the room. This one was wearing a yellow working helmet.
''Good morning Twilight, Fluttershy, Rainbow Dash, Applejack, Rarity and Princess Luna, nice to see you here. Conscience, what do you want ?''
''Can you please take my place for a bit ? I'm helping them to solve a case in here that may have something to do with the leader feeling thoughts.'' said Conscience.
''Pff, those good for nothing snobs start having problems, ay ? Go check them out, I'll stay on guard here. '' replied Common Sense.
''Thank you buddy, I'll be right back.'' said Conscience. ''Common Sense may be a bit grumpy, but he's actually a nice guy once you get to know him.'' she said to the group.
''So, what's the first place we should go ?'' asked Twilight.
''Well, the feelings are all nearby, as they're all here in the Prefrontal Cortex.'' said Conscience.
She then looked at the group and saw the confused faces that everybody had.
''I guess the first feeling we should see is Happiness. There you will find a Pinkie Pie, let's say, much more similar to the one you have outside. Well, shall we go ?''
The group then started marching, ready to venture into this new, unexplored, but fascinating territory.
