It was 3:00 AM in Equestria and a new student was going to attend Cheerilee's class the next day as an exchange student, a colt walks into Ponyville that night, he had a sky blue coat, a short white mane and tail, and pale yellow eyes, he did not have a cutie mark yet. The colt walks around town and looks around, he walks slowly to his home and looks around nervously, he sees his home and enters it, he closes the door and enters while sweating, he looks around while panting a little heavily, he lays down on the floor and goes to sleep while still having cold sweat go down his body.
The next day comes and the colt wakes up, he was still covered in sweat and sighs with relief, he gets up and heads to school. Cheerilee's class was loud and the students conversed, the door opens and Cheerilee enters with the new student coming in behind her, he stands at the front of the class with Cheerilee,
"Alright, class, settle down, we have a new student today, go on and introduce yourself." Cheerilee said, the new student's eyes dart around the room and he sweats a lot, the students notice it,
"Um, hi, my name is Walker, I'm four years old, um... I'm going to be a track runner like my father and paternal grandfather when I get older, I like art, I paint and study architecture in my free time as a hobby. Any questions?" the colt asked,
"Are you alright?" Sweetie Belle asked,
"Yeah, you seem so nervous." Scootaloo said,
"Sorry, I'm still new here." Walker replied,
"Um, you mentioned your father is a professional track runner, right?" Pipsqueak asked,
"Yes." Walker replied,
"What does your mother do?" Pipsqueak asked,
"My mother's dead." Walker replied, the class looks at him with stunned silence,
"Oh, I'm sorry to hear that, Walker, but please go on, do you have anymore questions for him?" Cheerilee asked,
"Who's lookin' after ya?" Apple Bloom asked,
"My dad and granddad." Walker replied,
"Your mommy's daddy?" Sweetie Belle asked,
"No, my paternal granddad, my dad's dad." Walker replied,
"What about your maternal grandparents?" Sweetie Belle asked,
"They died before mom and dad married." Walker replied,
"How about your dad's mom?" Scootaloo asked,
"She's dead, too." Walker replied, the foals look at him with widened eyes',
"Anymore questions?" Walker asked, the foals notice Walker trying to keep himself together, they were silent,
"I guess they're done, Walker, you can sit in that empty desk next to Sweetie Belle there." Cheerilee said, and Walker walks to the only empty desk in the class, he sits while Sweetie Belle looks to her left and smiles at Walker.
Class starts and everypony begins working, Walker, exhales sharply while he tries to concentrate, he writes and does his work while he glares at the paper. Sweetie Belle looks to her left and sees Walker had a very irritated facial expression, she notices him getting more and more angry as he worked, but he finished quickly and put the pencil down, he sighs with his eyes closed while shrugging, Sweetie Belle notices he was no longer irritated and went back to work. Walker looks around class and looks upward, his head moves from side-to-side slowly as if he was tracking something, he then begins looking around nervously and Sweetie Belle looks at him again, Walker seemed nervous as he looked around, she saw Apple Bloom and Scootaloo looking at him as well,
"Walker?" Sweetie Belle asked, he looks at her,
"Are you okay?" Sweetie Belle asked,
"Yeah." Walker replied,
"You don't seem okay." Sweetie Belle said,
"Just... getting used to my new surroundings." Walker replied while sweating profusely,
"Okay." Sweetie Belle said, and they all work until it was time for lunch. Apple Bloom, Scootaloo, and Sweetie Belle walk together and see Walker walking alone, they all have lunch and Walker sits alone, which the others notice, Walker eats quickly and leaves the cafeteria and goes to the bathroom. Lunch continues and Walker did not come back out of the bathroom, the foals get worried and Pipsqueak, Truffle, Snips, and Snails go to the colts' bathroom to check on him, the four gasp and exclaim with shock and the others hear them,
"He's gone!" Snails said, the foals look and their eyes' and mouths open wide, the four walk back and see the others,
"You guys didn't see him?" Button Mash asked,
"He's not in there." Snails replied, the foals look at one another,
"Maybe he's wandering around the school." Cotton Cloudy said,
"No, I've been watching, he never came out." Pipsqueak replied, the foals look on with confusion,
"Come on, let's finish our lunches." Snips said, and they do, they all have lunch and go back to class, the students look into the colts' bathroom and see Walker was not there, and all of the stalls were open, they look forward and head to class. The students arrive back in class and they sit, they all get back to work and see Walker was behind the last foal in their line, surprising the foals,
"Where were you?" Pipsqueak asked,
"Um..." Walker said as his eyes dart across the room and he sweats,
"Is something the matter, class?" Cheerilee asked,
"He left the cafeteria and never came back." Truffle replied,
"Did you go to the bathroom, Walker?" Cheerilee asked,
"Yes." Walker replied,
"We checked the bathroom, and he wasn't in there." Snips said,
"Oh. Walker, did you wander around the school?" Cheerilee asked,
"Yeah." Walker replied nervously,
"Do not wander around the school after you finish your lunch, Walker, your school may have allowed it, but I don't allow it here, now take a seat." Cheerilee said, and Walker did. The foals work and Walker was irritated again as he works, Apple Bloom, Scootaloo, and Sweetie Belle watch him, Sweetie Belle looks at Scootaloo and raises her eyebrows, Scootaloo shakes her head while shrugging while Apple Bloom just shrugs, Walker finishs his classwork and then puts his head down, he stays like that until the bell rings,
"Class is dismissed, see you all tomorrow, no homework today." Cheerilee said, and they all head home.
Walker heads home and trots as fast as he can, he arrives home and streamers go off,
"Surprise!" Pinkie Pie said, Walker looks and sees it was a welcoming party,
"Welcome to our town, exchange student." Mayor Mare said, and the party starts. Walker walks around and sees a lot of games and treats to try, he decides to pin the tail on a donkey while blindfolded, he stumbles around and holds his front left hoof out, he feels a foal in front of him eventually and tries to put the tail on, the filly yelps. Walker tries again and walks around a bit, he feels what is ahead of him with his front right hoof, he feels a pony in front of him, he moves his hoof around and realizes it was somepony's face,
"It's me, Walker." Sweetie Belle said,
"Oh, sorry." Walker replied, and he keeps wandering around, he feels a flank and tries to pin the tail, he hears Button Mash scream. Pinkie Pie runs to Walker and takes the blindfold off of him,
"Come on, Walker, let's try another game before you end up hurting everypony." Pinkie Pie said, and he looks around,
"Is there a piñata anywhere?" Walker asked,
"I got one!" Pinkie Pie replied, and she hangs up a piñata shaped like Princess Celestia. Walker begins hitting the piñata while the foals cheer,
"Say, what's he like in class?" Applejack asked,
"Weird." Sweetie Belle replied,
"Weird? How so?" Rarity asked,
"He seems mad while he's working, and he's looking around the class all the time." Scootaloo replied,
"He's probably just nervous about being in a new environment, he'll probably calm down after a few days." Twilight Sparkle said, they see Walker hitting the piñata and letting the other foals take turns, they all cheer and have fun, they break the piñata and the foals cheer as the candy fall,
"Wait, um, where is the kid's parents?" Rainbow Dash asked,
"Now that you mention it, I don't see his guardians anywhere." Fluttershy replied,
"They told me to go on ahead and come here on my own, they'll catch up here." Walker said,
"When did you come into Ponyville?" Rainbow Dash asked,
"Last night." Walker replied, Fluttershy gasps,
"Walker, you should know better than not to travel out alone in the middle of the night, it's too dangerous for kids to be out so late all by themselves." Fluttershy said,
"To be honest with you, I'm not safe anywhere." Walker replied,
"Yes, you are, you're in your new home, and home is the safest place for anypony, and you have the bearers of the Elements of Harmony in this town, you're super duper safe here." Pinkie Pie said, Walker just looks at her,
"Come on, Walker, try to enjoy yourself, we've got a lot of sweets and activities to do." Twilight Sparkle said, and Walker goes around. Walker looks around and sees the party cake, it catches his attention and he runs to it, he gets a piece of the cake and eats it,
"Hmm, this is good." Walker said, Pinkie Pie smiles proudly, he finishes the cake and looks around,
"Thank you, but I've had enough fun." Walker said,
"What? But the party's just starting." Pinkie Pie replied,
"I'm sorry, but I need to unpack my things." Walker said,
"Muffin?" Derpy asked,
"Thanks." Walker replied as he takes one and eats it,
"Thanks for the party, but I need to settle down." Walker said,
"Aw, you all heard him, the party's over, everypony." Pinkie Pie said, the ponies groan with disappointment but did what Pinkie Pie said and they all leave. Walker cleans up the streamers and confetti and decides to look around the house, he closes all the curtains in his house, he also locks the door and he sits on the floor while he waits for his guardians to come with his and their things.
Apple Bloom has dinner with her family,
"Somethin' weird happened with Walker today." Apple Bloom said,
"What do ya mean weird?" Granny Smith asked,
"He went into the bathroom during lunchtime, and he never came out, so four colts went into the bathroom to check on him, and he was gone." Apple Bloom said,
"Gone, as in?" Granny Smith asked,
"He wasn't in there." Apple Bloom replied, her family's attention is caught,
"What in tarnation?" Applejack asked,
"You didn't check with them?" Granny Smith asked,
"It's the colts' bathroom, so Ah can't enter." Apple Bloom replied,
"Still, keep an eye on him, Apple Bloom, that is mighty fishy right there." Applejack said, and they all have dinner.
Scootaloo was outside and seeing Rainbow Dash,
"Have you noticed anything strange about Walker, Rainbow Dash?" Scootaloo asked,
"No. Why?" Rainbow Dash asked,
"It's just that... when we were at school today, Walker went into the bathroom and never came out, so four colts went in to check on him, and he wasn't in there." Scootaloo replied, Rainbow Dash's eyes widen,
"Let me get this straight, you all had lunch, he went into the bathroom, never came out, so four colts went to go check on him, and he was gone?" Rainbow Dash asked,
"Yes." Scootaloo replied,
"That's weird, I explored the entire school once, there are no secret doors or passages built into it." Rainbow Dash said,
"There's more, when we went back into class, we were in a single file line, and Walker was in the very back, we didn't notice him until we sat." Scootaloo replied, Rainbow Dash becomes speechless,
"I don't know what to say, keep an eye on him, and tell me if you see anymore strange things happen." Rainbow Dash said, Scootaloo nods,
"You should head home, you shouldn't worry your aunts." Rainbow Dash said,
"Okay, bye, Rainbow Dash." Scootaloo replied, and she walks home while Rainbow Dash flies to her home.
Sweetie Belle was getting ready for bed while Rarity was closing the shop, she walks to her,
"Rarity, something weird happened at school today." Sweetie Belle said,
"What is it, darling?" Rarity asked,
"It's Walker, he went to the bathroom and wasn't in there when a few colts went to go check on him." Sweetie Belle replied,
"Surely, he just left when you all weren't looking." Rarity said,
"No, they watched the whole time, he never came out." Sweetie Belle replied,
"What? Now, obviously, he can't teleport, he's an earth pony, he has to have a secret." Rarity replied,
"Do you have any ideas?" Sweetie Belle asked,
"I can't say, I'll need to see for myself, off to bed now, darling." Rarity replied, and Sweetie Belle goes to bed.
