Jane is probably the worst written character of the series.
In S7, she is so obsessed with Spinner while also talking about how she’s not like other girls. He wants to rest because yano, CANCER, and she’s pushing him to party and go to concerts. She shames him for smoking marijuana (which obviously he shouldn’t have been hanging out with Darcy but at least she tried to be understanding).
In S8, I was really hoping for a redemption. She plays football, stands up to Spinner about letting her be her own person, comes to term with her childhood abuse.
In S9, she falls for Declan and decides to break up with Spinner, but then decides long term cheating is better? She never even comes clean, Spinner finds out from her and Holly J yapping. Then we never hear from her again. The writers did her so dirty
