I do like the aspect of Lucinda and John reconciling but Lucinda giving over the reins to Worldwide to Lily just doesn't quite ring true to the character. I agree with @Mitchthough that realistically, there would be a back and forth on who is running the company. I could see Lucinda, not meaning to undermine Lily but doing it nonetheless, until a struggle ensues over the direction of the company. Honestly, the show should've kept Lucinda's eldest grandchild alive so that he could be groomed to take over (even as Lily runs the company), that would've caused some friction, but alas.
