Best Night Ever
Tony doesn't know who is Spider-Man. Peter has become an intern at SI but no one at Midtown has found out, aside from MJ and Ned, who has become an anonymous Spider-Man inspired shitposter to curb his need to brag about his best friend. Through that they have gained many online friends.
Some big movie studio wants to make a musical about Spider-Man, so they hold a dance competition to find actors for Spider-Man himself and his love interest. Flash has partially bought his way through the competition and framed Peter for something so that he's disqualified, but Harley, who is participating with Shuri, whom he befriended through Tony, convinces the judges to let Peter dance without rating him, because Peter unknowingly vented to him that he, but more importantly, MJ, who he has a crush on and has asked to be his dance partner, has worked very hard for it and now they are sad that it was for nothing just because their bully wanted to be nasty. Flash dances OK, during his performance Harley and Shuri hacks and gathers proof that he cheated and framed Peter, but Peter thanks them for the chance to dance on the big stage and asks them to not make them requalify him because that's not why he participated. They reluctantly agree, but decide to still release the information at the end of the event.
Harley and Shuri are the last ones to be judged, and are the best ones so far. Then they (or the announcer or someone) explain that there is one more couple but they won't be judged. "Awake and alive" starts playing and Peter and MJ take the stage with a fusion of ballroom dances, ballet and street dancing. During the bridge when instrumental starts Peter grabs MJ, jumps on judges' table and leaps into the air, shooting a web, swinging over the stage and doing much more athletic and over-the-top versions of his previous moves, then at the end sliding down a web and finishing back on stage, where he throws a web dissolver bomb in the air to clean up the webs. MJ kisses him. She whispers "that was epic", Peter replies "you're epic". Then he looks up, throws down a sparkling smoke bomb and they run off stage, grab their things and run away. They change in a surprisingly clean alleyway, buy some popsicles and relax on a roof near a restored Stark tower. Peter takes a photo of the glowing sign and posts on Instagram with a caption "starkgazing #bestnightever #thanksharley".
Next day they are famous, Ned is kind of freaking out, Flash is being sued and Harley, who has found out that Peter is an intern, invites them to his lab to hang out with him and Shuri.
Sequel to "Best Night Ever". Peter wants to take his friends to the Tower, too. Harley says that he can just climb through the window into his lab, and Peter makes a web harness to carry MJ and Ned with him. They all science, eat pizza and have a good time. Later Tony wonders what Harley and Shuri are doing for so long in their lab, and FRIDAY tells him about Spider-Man and his friends. He quietly steps into the lab and says "you know that we have elevators in this building, right?". Peter squeaks and falls off the ceiling.
