Days passed by but Peter and Harley's path never really crossed. It's as if they're tracking each other's movements in the company just to avoid one another.

Peter wanted a break from the paper works and meetings which kept him occupied all day that's why he went to his hiding place—the lab inside his office, of course. He reviewed files and designs for his suit and made some adjustments in the formula for his web fluid. It's been a long time ever since he did it and man, it was relaxing. He was busy tinkering with these stuff until he noticed Shuri's report on what they termed as "detonator." Peter immediately called his fellow Avenger and asked her about their discoveries.

It turned out his initial theory that their quantum chamber would emit the same radiation as what the villain used was wrong. The detonator that the villain uses deals with the present matter. The subject must be in the present and it works with neurological process altering the mind. Tony's re-engineered particles would therefore not tamper with the signals they use to track the mad man since the latter alters reality, not time.

"That's it!" he exclaimed hitting the table and standing up. He grabbed his phone and rang Harley.

"Come on, come on! Pick up, Kee-"

"What do you want?" Harley's voice was stone cold.

"I figured it out!" Peter's, on the other hand, was warmer than sunshine.

"What?"

"The signal! The quantum particles that the person responsible for the mysterious disappearances uses were different from Tony's particles. We'll operate on different realms . I got it wrong"

Peter went on to explain Shuri's report and how he proved that his initial theory was wrong. Harley was silent but he still felt adrenaline surging through his veins as he ponders over how right the hero's proposal could be.

There was a long silence before anyone could say a word. Thankfully, it was Peter who broke the awkwardness of the moment. "I'm really sorry, bro." Unfortunately, it only made it more awkward. Great going, Pete.

"Wh—" Harley could not believe it. His ears may have been playing tricks on him but he knew he heard it right! He never heard this from Peter for a long time but it felt uh, right? He felt happy as evidenced by the beat that his heart skipped at the sound of his "brother's" apology.

"I'm sorry for saying those things to you," Peter replied immediately not giving Harley enough time to process the situation "I really don't mean them and that's not really it. I know I hurt you and I'm really sorry."

Harley can no longer hold back his smile. "Meet me at the electronics lab 73"

"Race you there!" answered the arachnid.

The two boys then started adjusting the sequencing they did from the last months of effort with their model. They built everything, computed and recomputed, until they came up with the accurate digits to use in their system. They connected and disconnected, wire after wire, circuit after circuit, both determined not to waste a single drop of the Pym particles(or shall we say Stark particles) Tony left for them.

After hours of sweat and effort, they finally were able to build a larger version of the model that Harley designed.

"Troubleshoot" said Harley

"Huh?" Peter responded

"Go troubleshoot, that's what you do best, genius" answered the former.

"Oooh. Okay" Peter then checked the system and the wires on the chamber. He stopped for a moment, solved some equations on the board then went back to fixing the system but he paused a moment while trying to sort things out

"Don't hold back" Harley said curious about what single brain cell of Peter stopped the younger man from continuing what he was doing. The results look promising after all.

"What?"

"Superhearing not working anymore? I said Don't. hold. back" Harley teasingly repeated emphasizing each of his words. Peter froze. Every single word registered and they brought back a treasured moment.

FLASHBACK

"Let's just go back, this is an awful idea." Peter said trying to turn back from the snowy hill in front of him. Harley placed his hand on the younger boy's back and pushed him a little to the edge of the hill

"What? you told me you wanted to learn how to ski." Harley stated

"Yeah. Uncle Ben was supposed to teach me but that was before. But I don't think I can anymore, the hill's too high and there are a lot of bumps and what if I slid down too fast and hurt myself or someone else" Peter argued

"Come on, we came all the way here. Let's do this"

"I…I don't know, Harley what if I don't know how to slow down or stop and crash at something"

"Look, Pete, it's a simple physics problem and you're better in physics than anyone I know"

"That sounds right." Peter concurred a little but was still hesitant "Are you really good at this?"

"Good? Naaah I'm the best" he said pushing Peter a little closer to the edge

"Woah woah woah!" Peter protested trying to push his way back "stop Harley I really don't want to"

"Just don't be afraid, Pedro. Tony taught me and one thing he said: Don't hold back"

"What?" Peter asked even though he heard every single word just to buy himself some time before sliding down the hill but it didn't work.

"DON'T HOLD BACK" and with that Harley used all his might to push his brother.

"Harleeeeeeeeeeeeeeeeeeeyyyyy" Peter shouted

"Woohhhoooooooooooooo" The blonde head shouted as he followed Peter.

"Keep your eyes open…ooohhh ohhhh…look ahead, Pete this is the best part" Harley went past him and made a 360 degree spin.

"Wooooow" Peter marvelled at his older brother who looked like he's defying gravity

Peter was enjoying the ride when he saw that he was approaching a bump.

"Uhhh…Harley…heeeeellppp"

"Physics problem, dude"

Peter then used his ski poles and tried to went over the bump

"Wooooohhhhoooo"

"Seee, you're a natural" Harley shouted. "That's my little bro!" he said shouting at the top of his lungs.

They simply had the time of their lives riding down the hill. When they reached the bottom, they had a little snow fight, made some snow Iron Man's and went inside the cabin for some hot chocolate.

"Thank you" Peter said with his cheeks blushing.

"For?"

"Mr. Stark said he'd take me here but…"

"No big, Petey. You're always welcome"

Peter smiled and took a sip from his mug. "You really like skiing, huh?"

"Yes, when I feel the wind through my face, it er…It feels like flying," Harley explained "That's why I don't hold back"

"I also dream that" Peter agreed with a huge grin on his face thinking that his idol has the same dream as he does.

"Don't worry, li'l bro,if I can invent a way to, I promise to take you with, Petey" Harley smirked and ruffled Peter's hair.

Everything else then followed popping out of Peter's memories—all the times Harley supported him in literally everything he did. He never really knew what happened between them but Peter can boldly say that Harley has been a huge part of his life. Even after he was bitten by the radioactive spider "Come on, Pete. It's a simple physics problem" was the thing he kept saying himself before he made the first swing.

And when he tried to rescue his Decathlon team in D.C., the monument was too high for him but he tried his best to overcome that fear and "Don't hold back" was the only thing he can think of before he took that jump. From then on, he kept saying this to himself each time he feels scared and alone, each time he goes on death-defying missions. Harley has inspired him in so many ways and he admired how his big brother was fearless and daring. Harley never showed signs of being afraid. He always makes things look easy and enjoyed himself just as how he does when he puts his heart in a project.

Peter just stared blankly at his older brother.

"Helllllooooo, Stickyman?"

"Oohhh. Right. Sorry. I think we just need to put this here and connect this there and…done"

"It's awesome!" Harley exclaimed as he circled the chamber they build with his eyes wide. Peter just stared at his brother still thinking about all the machines they build when they were younger. Harley never lost that sparkle in his eyes when they were able to build something together. Put two geniuses together and nobody will know how the world could be.

Harley looked back at him and said "So, should we fire this baby up?"

"S..sure you do the honors." Peter responded walking closer to him.

"Come on, darling. Let's see you work"

"Stop doing that, please"

"What?"

"Those endearments, it sounds gross"

"Don't listen to the Arachnid, love of my life…"

"Uhhh" Peter face palmed mentally.

Harley then turned the chamber on and that familiar engine-like sound and warmth from the lights filled the room. But due to Peter's enhanced senses, his excitement was replaced with the smell of burnt metal coming from the quantum chamber. After that, he heard crackling sound and his expression changed which caught Harley's attention

"Just give it a sec." Harley asked closing his fists and looking eagerly at the chamber "Come on, Come on, mi amore"

At the sight of smoke coming out of the chamber, Peter quickly jumped and grabbed Harley, breaking the window of the room and swinging to a safe spot on the ground as a loud explosion ensued. Fire and ashes filled the air and the employees needed to be evacuated. The firemen arrived and helped put the fire off. Peter immediately changed to his Spidey suit and helped evacuate civilians.

As they were able to get everyone to safety, he checked on the employees and the passers-by and thankfully, no one got severely injured.

"We're so dead" he scolded himself.
