how the end could save the season
This season has been rather meh for me. It's had great moments, sure, but overall, meh. Will giving up McCoy to do a solo surrogacy is dumb and desperate. Grace being pregnant is repeating a blah storyline from Season 8, which they retconned.
So there's the answer.
Retcon again.
In the finale (or sooner, so we can stop wasting time) they can do away with some of the stuff and say it was all a dream like they did with most of Season 8 in the opening of the revival. And then they could bring Vince back too.
