Ok so there's 3 chapters to the Day series here. Day with Optimus (this chapter) Day with Megatron and Day with Winterbloom (the next two chapters.) These all happen within the same day.

Enjoy!~

"Blurr, are you alright?" Optimus asked for possibly the 5th time in less than an hour.

"Y-Yeah.... I'm just nervous." The blue sparkling looked to the floor, shifting his weight from ped to ped.

"Oh, and why is that young one?"

"This is the first time I'm away from my mother and brother."

Optimus smiled softly at that. Getting up, he knelt before the sparkling. "Fear not, I am not frightening." Optimus poked his chassis. "How about we take a break from the office and go out?"

Blurr's face immediately lit up.

~~~~

Blurr walked by Optimus Primes side. Usually a sparkling would have a hard time keeping up with their parents strides, but Blurr easily kept up with him. Even if Optimus took abnormally long strides.

"So, where we going?" Blurr asked cheerfully.

"It is a surprise." Optimus smiled, stopping at an intersection where bots zipped by at high speeds in their alts.

The Prime was watching the road with his full attention, but suddenly he glanced down when small didgets wrapped around his own larger ones.

A smile came upon his face plates as he held Blurr's servo while crossing the street.

~~~~

Optimus and Blurr strolled up to an abandoned building.

"What is it?" Blurr asked.

Optimus chuckled. "It's an old racing circuit from 25,000 years ago."

Blurr jogged ahead, a huge grin on his facial plates. The structure of the building was ominous and gave him a sense of adventure.

"Optimus can we go in? Please!" The sparkling begged and the Prime nodded.

~~~~

Blurr gasped at the sight of the track. It was in bad condition but it still looked runable.

"Optimus, can we run?" Blurr asked gripping the rail with excitement.

The leader of the Autobots laughed, "If I were to run, you'd leave me behind." Blurr pouted at that. "But, how about I drive next to you?"

"Yeah!"

~~~~~

Blurr took a deep ventilation as Optimus transformed into his alt, rolling up beside him.

"Are you ready?" The Prime asked.

Blurr nodded with a smile, his struts growing tight and vents opening to their maximum length.

"Ready?" Optimus began and Blurr lowered to the ground. His body poised for attack. "GO!"

The roar of an engine bounced off the track as Blurr launched himself forwards. He dug his peds into the ground as he began his was down the race track.

{:Blurr, slow down.:} Optimus commed, his alt closing the distance between him and the sparkling ever slowly.

{:You're to slow!:} Blurr laughed taking the sharp left turn, dragging his servo along the ground to help balance.

Ahead were obstacles and the sparkling welcomed them.

(Memory of when Blurr was younger and in the races before Optimus adopted him)

"GO BLURR GO!!! GO BLURR GO!!!!"

The crowd cheered as the blue bot vaulted over obstacles and slid underneath walls. His opponents doing the same, but at a slower rate.

Blurr was built for this. Jumping over obstacles at high speeds, faster than any seeker. A simple trip could rip his leg off or leave him with no limbs.

This, was what he was built for, what he craved.

The sparkling jumped over the final obstacle and was on the driving part of the course. Where alts were to dodge the stationary ground obstacles, but all he could do, was slide left and right to avoid them since he didn't have an alt.

Suddenly, Blurr heard the loud engine of Optimus beside him making him jump.

"H-how did?" He tried to ask over the roaring wind but the truck pulled ahead, and faintly, Blurr could hear laughing.

Growling, the blue speedster ran harder in hopes to catch up but quickly, he dug his heels into the ground trying to stop at the sight of Optimus transforming before him.

"Gahhh!" The sparkling screamed as he slammed into the Prime, pushing them over the edge of the broken race track.

Optimus quickly grabbed Blurr and pulled him close, wrapping his arms around his small frame as they fell below the race tracks structural support pillars and into the fallen debris at the bottom.

Optimus made sure to hold tightly to the sparkling as his frame connected to the ground, knocking him into stasis.

~~~

Blurr onlined his optics to see red and blue armor wrapped around his frame. Slowly he sat up to discover he was being protected by Optimus Prime.

Blurr placed his servos on either side of the Primes face. "O-Optimus.... wake up. Optimus." Blurr's vocalizer fritzed. "D-Don't leave me.... Optimus..." A tear fell from the sparklings chin onto the Primes chassis.

"Ugh...." The Autobot leader groaned, turning his helm.

Blurr watched with relief as the Primes optics came online.

"Blurr." He said, "I would never leave you."

The Prime suddenly felt small arms wrap around his neck as he embraced the sparkling in a comforting hug.

~~~~~

The sun was starting to set as Blurr and Optimus walked down the Iacon shopping district.

It took them nearly 3 hours to exit the race track but both seemed happy with their results for the day.

Optimus however, had another surprise up his sleeve. "Blurr." The blue sparkling walking by his side looked up with curious optics. "Are you hungry?"

Blurr nodded and Optimus led them into an old bar that was closed for the evening hours. Upon entering, a loud, ruff voice made the sparkling cower behind the Primes ped.

"Don't you know how to read? The sign says closed!"

Optimus smiled, "it is good to see you Firetrail." Optimus smiled kindly towards a red bot behind the bar.

He was tall, almost Optimus's height and bulky like Ultra Magnus; but the scary bots optics held kindness in them. It appeared that he was just having a rough day.

"Optimus, it's been ages." The red bot known as Firetrail laughed, walking around the bar to hug the prime, his friend.

"Indeed it has old friend."

"What can I do for you?" Firetrail asked with a smile, servos on his hips.

"I wish to buy some of your famous Energon Soup for my youngling here." Optimus shifted so Firetrail could see the sparkling hiding behind his leg.

"Well, isn't that just adorable." The red bot smiled. "Have a seat anywhere. I'll get yall some grub. Oh and Optimus." He turned. "It's nice to see you again."

"Like wise."

~~~~

At first, the Energon Soup didn't look appetizing to Blurr. It's blue chunky parts floated in a warm broth seemed to make his tanks churn.

"Blurr, try it. You may find you like it." Optimus smiled to the sparkling with encouragement.

Hesitantly, Blurr lifted the spoon and shoveled a small portion of the soup in his mouth.

Optimus watched as the sparklings face quickly grew to surprise then to seeing him eat more. "See?" Optimus gestured.

"Thank you!" Blurr said in between bites.

Firetrail was behind his bar with a wide grin on his face, "Looks like I'm gonna have a regular when he grows up."

~~~~

Optimus held the door open for Blurr to exit, Firetrail coming up behind to speak to the Prime.

"Optimus..... If you ever need me. Know that I am here."

"I know." He smiled kindly to the bar tender and turned to leave.

~~~~~

"Hey Optimus." Blurr drawled out while skipping next to the Primes side.

"Yes?"

"Do you think I can become a racer one day? Like a famous one?"

The Prime rose a brow at this. 'Did he not want to become an Elite Guard like he was in the past?'

"You can be anything you wish." Optimus said as they strolled up to the Primes living quarters; a large mansion.

"I can't wait to race. Maybe then, if I win, I can help my mother and brother with anything." The sparkling smiled as he entered the door.

Optimus couldn't help but chuckle at that.

Well, there's the first one and I'll have the next one up in a few. Just gotta proof read it... I hate proof reading...
