I am glad at least some of the plot from the first half still exists. I wasn’t sure how much they were going to try and start over. Though they are attempting another villain sob story and probable death which I could do without.
Well they probably already had an idea that this would be the last Season, by the time they were writing the 2nd half. Either way, right now their priority is to wrap up what they can in the remaining episodes, so it wouldn’t make much sense to set up a bunch of new stuff now.
