Was it stated either how much time had passed between Painful Evacuation and Gummies? Because it felt a bit odd how quickly Adam and Jessa had progressed with their movie… Either way, totally with you that if given less screentime especially without specific scene for scene recreation’s, the storyline could have been serviced better.
I think across the shows entire run, there has never been enough Shoshanna, she always gets weirdly sidelined. It’s certainly frustrating that her story arc (getting back together with Ray, surely?) seems to have been inevitable since the beginning of the season. Hopefully we’re proved wrong and she gets a really juicy storyline over the last four (!) episodes.
