If Eric had arranged a private jet for Ivy through the company, perhaps what happened with Liam would be possible. Though due to the current laws, this happening on a commercial flight is impossible and improbable.
The Robin and Jason bridge scenes rewrote Jason and Robin's history. Sonny wasn't why Robin and Jason broke up, but Robin telling the truth about Michael's paternity. This is why Carly hates Robin's guts as Robin tore Carly's life to shreds once that information was revealed. (Robin and Sonny's friendship only went bad years later.)
Phyllis helped Billy relaunch paragon to get back at Victor, but Jack finally telling the truth and doing the "right" thing she gets upset. That makes no sense. The little girl is the younger sister of Emma on GH.
I agree that the only reason we see Bill and Katie is the actors. They are popular even with the lack of airtime. Maybe Winsor got another job or won't be anywhere near LA, I hope we don't get Thorne's death at Christmas.
