“I think that’s everything. Did you get all that, Rainbow?” Fluttershy asked sheepishly, but with a sterner look on her face.

Rainbow absentmindedly blinked upon noticing Fluttershy was finally done speaking. The rainbow manned pegasus never thought someone other than Twilight could go on and on about nothing, but since Marcus is a different species, it’s only fitting for the usually timid pegasus.

“Yeah, of course,” Rainbow scoffed with a cocky smile, “No worries, Flutters. I will take good care of the little guy. I am his best aunt after all.”

Before Flutters could respond, both ponies' vision was filled with a poofy pink mane, as Pinkie appeared in between the two.

“I am his best auntie as I shower him with the best sweets ever!”

“Fine, coolest aunt,” Rainbow conceded with an eye roll.

“That will work,” Pinkie agreed with a smile, “Well, better get back to the order frenzy. It’s one of the busiest times of the year for the cakes and they need my help,” She finished before disappearing as quickly as she came.

“Trust me Flutters I will take good care of him,” Rainbow assured her.

“Ok, if you think so. We should be gone for most of the day,” Fluttershy responded before a knock was heard at the door.

Fluttershy slowly walked to it and opened it revealing Twilight, wearing saddlebags and an eager look on her face.

“Good morning Fluttershy,” She greeted enthusiastically, “Oh and you too Rainbow,” She continued sheepishly upon finally noticing the cyan pegasus.

“Good morning, Twilight,” The two pegasi greeted back.

“Going to watch over Marcus, Rainbow?” Twilight asked with a raised eyebrow.

“Yeah, of course.”

“Rarity, Pinkie, and Applejack were all busy,” Fluttershy explained.

“Hey! Why do you consider Pinkie better than me when she gives him too many sweets?” Rainbow asked bitterly.

Both ponies were stunned by that valid question and simply stared at each other in silence for a few moments.

“I guess that is one thing I don’t have to worry about with you,” Fluttershy conceded.

Rainbow simply rolled her eyes.

“Anyway, we better get going, Fluttershy, if we are going to make it on time to plan out Marcus’s own bedroom and get him everything he needs,” Twilight finally told her.

“Right. Well, Rainbow, take good care of him.”

“Yeah, yeah. His coolest aunt is on the job!”

Marcus gently rubbed his eyes, as he walked into the living room. Normally, Fluttershy would have woken him up by now, but he figured she decided to let him sleep in.

“Finally awake squirt?”

He stopped rubbing his eyes and instead of Fluttershy, he was greeted with Rainbow Dash, who was giving him a cocky smile.

“I see I am not the only one who likes to sleep in, though it was boring to be the one waiting for once,” She added with a shrug, “No matter. Your coolest aunt, since Pinkie is insistent on taking the best title…”

She was momentarily interrupted by Pinkie appearing to stick her tongue out and blow a raspberry.

“Will be taking care of you, since Fluttershy is off doing egghead legal stuff to finally get started on your own room and stuff,” Rainbow continued without missing a beat, “Now we get to spend the whole day together just you and me. I can finally give you that ride without Fluttershy breathing down my neck.”

“Ok auntie Rainbow.”

“Now, might as well have breakfast before our fun. I kind of skipped out since I was in a rush to finally give you a ride,” Rainbow admitted kind of sheepishly.

Rainbow and Marcus entered the kitchen and Rainbow quickly rushed to the fridge, only to find a note taped to it.

“What’s this nonsense?” Rainbow asked.

Rainbow, he likes his eggs sunny side up. I will explain how to make it since you aren’t the best cook, if you don’t mind…

“That was just that one time. Gilda was distracting me when I did that!” Rainbow complained bitterly, before giving the concerned human a nervous expression, “Uh… So, I know how you prefer your eggs, and I will prepare it right,” She assured him, scoffing at Flutters not trusting her to take care of him.

Rainbow grabbed the whole carton of eggs and rushed to the stove, determined to prove her close lifelong friend wrong.

“Stupid Flutters. Not trusting I can be responsible and take care of a colt. I will show her,” She muttered, as the eggs were being cooked.

She was so focused on her thoughts, that she didn’t pay attention to the cooking eggs and before she snapped out of it, they were burning.

“What’s that smell?” She asked, before groaning at the now burning eggs, “Come on! I’m supposed to prove Flutters wrong.”

She took the eggs out of the pan and decided to have these be hers, to try and hide the fact she burned them. She then took a couple more eggs and cracked them on the pan.

“Stay focused Rainbow. You can’t burn these ones,” She assured herself.

Meanwhile Marcus was sitting at the table, waiting for his breakfast. Rainbow was taking longer than Fluttershy and was wondering what was going on. A couple minutes later Rainbow returned with a plate of decent cooked eggs and a fork.

“Here you are, and I didn’t screw them up. Go ahead and tell Flutters she can trust me to cook for you.”

Before Marcus could respond Rainbow rushed back and grabbed her own plate of burned eggs.

“Now let’s eat.”

“Auntie Rainbow, those look burnt.”

“No, no,” Rainbow denied with a nervous scoff, “I like them more well done than you do,” She slowly managed to take a bite and tried not to gag, “Yummy. Now let’s eat and we can have our fun.”

“Uh… Ok.”

After breakfast the two left the cottage and walked into a clear area outside.

“Alright, I am finally going to give you your ride without Flutters to get in the way,” She explained to the slightly nervous human, “No worries. I will be careful, and this will be fun. Now get on my back.”

Marcus carefully climbed on top of Rainbow and gently wrapped his arms around her neck. Rainbow found herself enjoying the touch of his soft skin on her fur. Perhaps this is the reason Flutters always carries him on her own back.

“Wow, this reminds me how little you are for someone on two legs,” Rainbow teased with a smirk, “Now hold on tight,” She added before slowly taking off.

Marcus, with his eyes closed, felt himself and Rainbow rising in the air for a few moments, before she stopped in midair for a brief second, then she slowly began moving forward. The human managed to find the courage to open his eyes and was amazed at the sight of slowly moving along the air.

“Since I don’t want Fluttershy to find out and think I am un-responsible, or whatever egghead word Twilight would use, we are going have to go slow, but we are still going to have fun,” Rainbow assured him, “Even going slow I am still your best aunt.”

“I am!” They heard from below.

Rainbow looked down to find an annoyed Pinkie glaring up at her and shaking her hoof in anger.

“Coolest aunt.”

“That’s better.”

“Anyway, let me show you the sight of ponyville up in the air.”

“Ok,” The human agreed.

The pegasus took off, going a little bit faster than before, but not too much that the human had trouble staying on. Marcus tried his best to stay still as possible, to not lose his balance, which was a bit difficult to do. In no time the two were flying above ponyville and Marcus was stunned to find from up there the ponies looked like big different colored blobs moving around and interacting.

“Looks like blobs of paint moving around or whatever, huh?” Rainbow spoke up with a chuckle, “One reason I love flying. It really makes you feel different. You feel more special and freer. The sky isn’t the limit and once I join the wonderbolts I will be even cooler about it.”

The two continued to fly over ponyville and watched the ponies go on with their daily lives.

“About time I got to do this, since Flutters was being overprotective,” Rainbow scoffed, “Never thought she would ever have the guts to be like that, but I guess having a colt to care for made her so,” Rainbow speciated with a thoughtful look, before shaking her head, “Anyway, let’s enjoy the rest of this flight.”

“Ok.”

After their flight around town, it was getting close to lunch and Rainbow decided to buy them food from Sugarcube corner. Once the two went inside they noticed it was almost full, with a moving pink blur quickly handing out orders, while Mr. and Mrs. Cake were doing so as well at their own pace.

“Huh? This place is packed after all,” Rainbow commented, while looking around for a free table, "Come on we might as well wait,” She added with an annoyed sigh at having to be patient, before she smirked when she got a brilliant idea.

Once the two got to a free table, Rainbow gazed at the hyper pink blur with a smirk, before giving Marcus a smile.

“Don’t worry little dude I will get us food right now, as your best aunt.”

Suddenly, the pink blur stopped in midair and upon trying to find her location, made a loud gasp, before she suddenly appeared at their table, with an annoyed look like before.

“I am! Anyway, I was so busy I didn't notice you two,” She greeted, changing her angry expression to a sheepish one, before giving the human a quick nuzzle, “As your true best aunt, if I had noticed I would have given you your usual sweets.”

“We will take our usuals and only give him one portion this time,” Rainbow told her.

“But Dashie I must shower him with-”

“You must not spend too much time with us due to all the other waiting ponies,” Rainbow argued.

“Touche,” Pinkie conceded, before rushing to get their order.

After getting lunch and managing to stop Pinkie from giving him more sweets than Rainbow figured Fluttershy would tolerate, the two went back to her cottage. They ended up playing a few board games, where Rainbow decided to go easy on him…

“You owe me one thousand bits for rent.”

“Come on little guy. I will pay you back next turn.”

“Ummm,” He placed a hand on his chin, as Rainbow lightly sweated and waited for his answer, “Nope. Tough break auntie Rainbow.”

…Only to realize she didn’t need to, as the human was more ruthless at the games than any pony could be.

“Me the best pegasus in Equestria keeps losing to a colt,” Rainbow grumbled.

“Want me to let you win, auntie Rainbow?” He suggested with a chuckle.

“Oh, ha ha ha. Very funny,” Rainbow responded playfully.

Suddenly, they heard Fluttershy and Twilight enter the cottage and Fluttershy quickly rushed right up to the two.

“I’m finally home, Marcus!” She exclaimed, as she embraced him in a hug, “Oh, it was hard being away for a day, but we managed to start planning the construction of your new room.”

“When will it happen?”

“It will start next week. Plenty of time to prepare getting my animal friends situated and while it happens, we are going to have to stay at Twilight’s.”

“Where I finally can run some tests on…”

“Only the ones we agreed to Twilight,” Fluttershy reminded her.

“Of course. It’s still exciting.”

“How was it with Rainbow today?” Fluttershy asked him.

Marcus pondered that, before giving Rainbow a smile, which she returned, with a nod.

“Auntie Rainbow was awesome. She is my best auntie ever.”

As soon as he said that Pinkie appeared with a stunned look on her face.

“No, you can’t…” She tried to say only to pass out.

Marcus, Fluttershy and Twilight were concerned, while Rainbow simply chuckled.

“Take that Pinkie. I am the best as always!”

“Not at board games auntie Rainbow,” Marcus quipped, making her frown and blush in embarrassment.

“Yeah, well…. I am still your best aunt.”

Poor Pinkie She needs to learn kids will keep on going back and forward quickly and easily. All she needs is her own day with him and she likely will regain her best auntie title.
