Yeah I see now what you wrote. I don’t think it’s a retelling necessary . I think it was a little of both, she stayed for Gwen and Peter. Maybe the piece should have said it a little differently since you don’t want to lose the fact that MJ did stay at n Peters behalf too and not JUST for Gwen.
Although if it had not been Gwen who died, I don’t think MJ would have stayed in that scene. I think that’s the point it makes which is worth showing.
