If you are going to continue your Spideypool fanfic, then can you write a chapter Involving Loki?!
Basically, Loki finds out about Peter's current situation, and decides to help the Avengers, only to learn that THEY were partially responsible for the creature taking over Peter's body, especially when he reads Tony's and Bruce's minds!!! When Tony argues that they were doing it because they care for Peter, Loki answers back angrily by stating that if he TRULY cared for him, he and the rest of the Avengers would have understood his reasons for being Spider-man and helped him get better at it DESPITE his age!!! He tells them what being a hero is REALLY about, and that Peter has made way more difference than the Avengers, who are a pathetic excuse for heroes, ever will!!! He chews them out even further over their complicity in Peter's current state, and once he's done, he states that he will get Peter back, but he will not be doing it for them, but for Peter, himself, and Wade, who has been in a great deal of emotional pain due to Peter's absence!!!
(P.S You can change the parts you hate, and maybe add some more)
