Just like Will's declaration of love to Mike, while feigning to be Eleven, Jake tells them that he has met Spider-Boy, and he has told him that: "Spider-Boy doesn't want others to find out about his secret identity, because he's afraid, every single day. Not for himself, but for his loved ones. He has his parents, who he admires, they were his heroes, and Spider-Boy wanted to be a hero just like them. His friends, the Avengers, feel the same for their parents. Sometimes he does nightmares, seeing his parents, or his friends, dead, with Spider-Boy not having been able to save them. This fear, on each day, since he started this hero journey, always devours him alive, because his parents and his friends are his stars of hope, little, but not to be ignored. But he can't allow himself to show fear, and so he pushes through that fear to fight for his stars, and for what he believes, because he knows, deep down in his heart, what he's doing, is right. Spider-Boy has teached Jake that being brave doesn't mean to not be afraid, it means to find the strength to push through that fear to do what is right, and never giving up until the very end.
Jake had spoken so passionately to them, that Will and Mike are deeply moved by Spider-Boy's intentions.
Through, days later, Will starts reflecting on what Jake had said, and remembers that same conversation that Will had done to Mike 30 years ago when he was confessing his undying love to him, while feingning that it was Eleven who spoke those words, and starts to find out that this same conversation is pretty much similar to Jake when he told them about Spider-Boy. Mike starts to think the same thing, and they both reach the final conclusion when the symbionte invasion begins, and they can't find Jake anywhere because he has gone, alongside the Avengers, to fight against Venom and the Symbiontes.
Jake Wheeler-Bylers is Spider-Boy.
Then the other parents will find out the same thing about their childs being the famous Avengers.
