Onto the next arc: Ultimate Fallout!

This arc would begin right as the last one ends, with the League of Villains and Sinister Six leaving the summer training camp and forcing the still capable students, the ones who are still standing, to gather up all their incapcitated classmates and try to stop Felicia from dying of poisoning. Thankfully, Momo remembers that Peter had borrowed Momo once to help him and Hatsume (Momo and Hatsume herself had got off on a rocky start thanks to Hatsume wanting to use Momo as a way to make more of her babies, but Momo had eventually got it into her head that Momo didn't like being treated that way, and the two of them had become friends soon after) figure out some chemical compositions, and was told that they had been working on an antidote to Scorpion's poisons, including on how to nullify its lethal effects, and calls Hatsume to see if that antidote was ever completed. To her eternal happiness, Hatsume had completed it, and when the poisoned students, as well as Felicia, arrive at the hospital, they are able to mass produce the antidote and administer it to them, nullifying the poison and saving Felicia's life.

Meanwhile, Peter wakes up from unconsciousness, drifting in and out of consciousness from the poison, tied to a chair and with metal restraints holding him down, and comes forth to an argument between Shigaraki, All for One, and Goblin, who admits to having neglected to pick up Bakugo out of spite of All for One holding him back from completing his goals earlier in their partnership. Shigaraki, in a rage, would try to kill Peter in retaliation, only for Goblin to hold him back and order him to stand down. It was Goblin's turn to call the shots, not Shigaraki or All for One. He wasn't going to be taking orders from them anymore. Peter slips back into unconsciousness.

At U.A., the heroes gather, and consider what to do now. At first, immediate punishment on Felicia for her part in the attack is demanded, but are put under consideration when several of the students, especially both Peter's friends and the ones that she helped save from the villains back in the forest, speak up in her defence, much to their confusion. As such, that problem is put on the backburner whilst they figure out how to retaliate against the villains.

Luckily, they have a breakthrough, as Felicia is conscious again, and has revealed to the heroes where the League and Six are based, and how she had been able to sneak a tracker onto Scorpion whilst he was stabbing and poisoning her.

Back with Peter, he wakes up once again, and is put face-to-face with Goblin once more. The two of them have a talk that they should've had a long time ago. Goblin reveals how far his hatred for Spider-Man, and by extension Peter, runs, made worse by the fact that he had once considered Peter to be a son to him, which only makes the supposed betrayal even worse. Now, he blames Peter for everything that's happened to him, especially Harry, and even Emily's deaths, and Peter shoots back that everything that happened to Goblin was because of Goblin himself, not Peter, nor anyone else. It is during this conversation that we get the reveal that Oscorp, before it went under thanks to Norman Osborn's crimes, had been the one to create the radioactive spider that bit Peter and turned him into the hero that he was today. Worse yet, Peter's childhood friend, outside of Harry, was Gwen Stacy, and Green Goblin had killed her during one of his attacks on the city, worsening the mutual hatred between them.

Finally, Peter asks what Goblin wants with the Infinity Stones, and Goblin makes his intentions here:

He wants to bring his wife and son back to life.

Peter is shocked by this, and Goblin explains that he seeks to bring back everything that he has loved, and the things that he loved the most were his wife, Emily, and his son, Harry. As such, when he gains all four stones, he will use them to bring back his wife and son with just a snap of his fingers, and he can go back to being a family with them. But, when Peter says that he could've helped him with bringing Emily and Harry back, Goblin sneers at him for it. His hatred and resentment of Spider-Man runs way too deep for him to even consider it. Worse yet, Goblin is either unable or unwilling to accept that he was horrifically abusive and neglectful to his son after his wife's death, and refuses to accept that the two of them would utterly despise Norman for what he has done, to Harry, to Peter, and to everyone else.

Goblin leaves, and allows the rest of the Sinister Six move in to have their own fun with their most hated nemesis. And thus would begin the long torture of Peter Parker.

Back in the hospital, Felicia and Momo talk with each other, where Felicia reveals her own past, in that she had been raised in poverty alongside her father, Walter Hardy, who had trained her to become a cat burglar in order to steal the food they needed to survive, and then the items that they needed to sell to make money, then it just kept going on and on and on, until eventually, when she was fourteen years old, she was breaking into rich people's homes and stealing their stuff right out from under their nose. By the time that she had come across Spider-Man, she had lost her father to a police officer, who had shot him in the head for stealing for someone he was on the payroll for, solidifying Felicia's hatred of authority.

Felicia didn't hate her father. In fact, she had loved him, much to Momo's surprise. He wasn't abusive, but they had to make due in a world that wasn't willing to give them a chance. She had had no choice in breaking the law. It was simply the circumstances that she was born into.

However, when she finally met Peter, met Spider-Man, she had found within him a friend, and maybe even something more. She had found in him a fragment of a happy childhood that she had never had. When Harry Osborn, one of Peter's childhood friends, had died, Felicia and Gwen Stacy, Peter's other childhood friend, had been there to comfort Peter over the loss, just as Peter had been there to comfort Felicia over the death of her father, and then, when Gwen died to Green Goblin sometime later, Felicia had helped him through the loss. The two of them had got into a brief romantic relationship with each other, but neither of them were emotionally mature enough to maintain it, and Peter was still mourning the loss of Harry and Gwen, and too consumed by grief to be able to cope with being with another. It was too soon after Gwen's death, the loss of the first woman that he loved, and the two of them mutually ended it, thankfully still being friends afterwards, if on a strange basis of one being a vigilante and the other being the thief they were supposed to catch.

Momo is stunned by this story, and conflicted on what she is supposed to think about it. She has always been taught that villains are people that do heinous things just because they want to, and that heroes are, well, heroic because they stopped the villains, and nothing more. That was what everyone who was born into hero society was talked. But she had never considered the possibility that someone may be forced to become a villain because they had no choice. Then, she remembers all the former and reformed villains that work in and attend F.E.A.S.T., including Twice, Mr. Compress, and Gentle Criminal and La Brava, and would begin to wonder as to what else hero society had neglected to teach them.

But that would have to wait, as all the able bodied students, or at least the ones not still in bed due to injuries or recovering from Scorpion's poison, gather around Momo and Felicia's beds and discuss what to do next. Many of them consider staying put and waiting for the heroes to rescue Peter. However, several other students, and Felicia, counter that the Sinister Six hate Spider-Man with a passion, and will no doubt be taking out that hate on him right now. They won't kill him, at least not until they've made him suffer. But with Aunt May there, they might've killed her already just to make a point to him. If they needed to move, then they needed to do it now. Plus, they might be planning on moving him out of the hideout, meaning that if they don't act soon, they might've ditched their current location and moved on, and Peter would be lost to them forever.

As such, Felicia frees herself from her restraints without much efforts, and makes plans to infiltrate the Sinister Six's hideout and rescue Peter and May, seeing as even with All Might there, the pro heroes have no idea what they're walking into and might not be able to get him out themselves. Plus, she'd managed to sneak another, more hidden tracker onto Scorpion, meaning that if they did move on, they could follow him and the rest of the League back to their next location if they find the first tracking device. Some of them agree to go with her, mainly Kendo, Tetsutetsu, Kirishima, Todoroki, Ochako, and Izuku (he might have a frosty relationship with Peter, but he's still Izuku, and he still wants to save as many people as he can. Momo would wish to go with them, but her injuries would keep her bedridden. However, the rest of the students would be unwilling to go, particularly Tsuyu, who would point out that this plan was super illegal and would get them all into trouble and considered villains themselves, and Iida who would be completely against this plan, his bias against Peter not helping as he points out that this would make them all vigilantes, and that associating with a criminal like Felicia would only make things worse for everyone as well.

Soon enough, the able-bodied students, few as they were, would go back to attend to their bedridden friends, while the rescue squad would be provided walkie talkies by Momo, and would get on their way. However, Iida would end up tailing behind them, wanting to stop them from going too far before they get themselves into trouble that they can't get out of...

And here we are, with some heartfelt conversations and dire truths being revealed... and the next arc to come, oh the next arc to come...

I think those who are reading this will have some... thoughts, about it.
