The "break up" of Jason and Carly -- then redirection toward Sonny and Carly -- is exactly why I wanted Sonny to walk in on Jason & Carly in the act after the latter's 2021 wedding. It would have been history in reverse and lead to all sorts of complications, especially because 2021 Carly and Jason seemed to be falling in love.
It's crazy how much 96-00 Sonny, Jason & Carly still affects the plot directly today! Even moreso evident as Nelle was written as a parallel to Carly. I loved when Carly got her just desserts after being falsely accused of pushing Nelle down the stairs, in parallel to what happened with AJ.
Robin was getting to be way too virtuous, they needed someone to knock her down a bit and balance it out. There was a point after Stone when it felt like everyone was her damn friend and was so concerned about her for months.
