Guilty of what, however?
Being a victim?
Being kidnapped against her will and sent to a dead dystopian world where she saved Peter but was forced to fight for her life against monsters?
Being "chained" by fake kids and hunted by a murderous madman for four years?
Having undergone what would be severe trauma resulting in what should be a serious case of PTS? Bonding with the only other human being on that planet, on whom she was forced to survive, resulting in a trauma bond? Trauma and stress reshape the brain. And anyone would do the same in that situation. Humans are social animals. We band together for survival.
Being stalked by Peter, who didn't once ask if she was okay or needed help but instead proceeded to act like his possession was stolen from him?
This run actually deserves negative stars. I see red whenever I think of the situations Wells put MJ in, only for no one - Peter or apparently the majority of readers - showing her any empathy for the trauma she was put through. Of course, the story treats what should be a highly traumatic and nuanced situation as if MJ went to Starbucks for a few hours and came home with Paul, which is wholly the fault of the writing. The writing to date deserves all the criticism it rightfully receives and then some.
Peter is also terribly written as well, let me be clear.
