I feel like the ski lodge chapter would be the perfect season 4 opener since it's a bottle episode focused on just the four of them. Season 1 and 2 ended on what ended up being Loid focused chapters, but I don't think it was intentional. As long as their last episode isn't focused on a side character like Franky or something, they'll probably be comfortable with either the dance party, Yor and Anya helping Mr. Authen, or even the final exams. Those have at least one of the Forgers at the center of the story, so they'd be decent places to end on.
