The theme of this episode is men are assholes, especially Jason.
In the wake of Sandy’s death, there’s no mention of him at all. Makes sense given the type of the show this is, but it’s still kinda weird. They were probably thinking it would be bad for re-runs.
Mike and Julie are continuing to keep their relationship a secret. The rest of the Seavers come home with Wally and Irma. The weird thing is Mike, who was making out with Julie before they came home, felt the need to go into another room. It’s not like he could’ve just been hanging out with Julie. Irma and Wally are getting married on the same cruise that they met, and the rest of the Seavers (including Julie) are coming along.
