I find myself fast-forwarding through the possession storyline. I remember the first iteration many years ago, and it was very different. I was happy to see it end when it did and I have no interest in it at all now. It's so stupid, not the least bit entertaining. I enjoyed seeing some old characters come to life, but that could have been a Halloween dream episode, and there were better ways to get to Allie telling Tripp she loves him (not sure I believe her) and Rafe and Nicole on the office table. Seeing Nick and those flashbacks reminded me what Gabi has been through, but that story could have been done differently, too.
I can't see how this continues much longer. Even if they want the demon baby story (I hope not), they could end Marlena's possession and make it so that she doesn't remember anything she did as Marl-atan. In other satanic baby stories (sadly, this is a thing), the pregnancy moves quickly, so it could be that the baby is spawned before Christmas.
