Gwen was bitten by a spider when she was hidding from the security with Peter (falshback), and after 6 months, she gets back to life as a spider-lady (woman). She wakes up from death (because when you are a spider, you body heals by itself) and helps Peter to find how and why his father died. His aunt gets old and dies. Gwen takes the interview to go to Englad again and makes it. Peter said that he was going to follow her whenever she goes, so he goes to England with Gwen.
Spider-man now knows all about his fathers job and goes to school to know more about chemicals and stuff (his fathers work was hard?). Harry will follow them to England, and by then, Gwen and Peter are done with school and knows how to defeat Harry using chemicals. They get married and have a child with even a greater power. The Great Spider-baby <3.
ALL I WANT IS, GWEN TO GET BACK WITH SPIDY.
