The episode features guest star Molly Ringwald, best known for her string of hits in the '80s but more recently a featured player on Raising Expectations and The Secret Life of the American Teenager.
When she comes to town, it seems as though Mary Andrews might be coming to codify what we've already seen: she and her husband are basically through.
“When Archie’s mom comes back, the stuff with Fred and Hermione looks as though it’s going to come to an end. Archie’s mom figures out what’s going on between them so there’s no rekindling for [Archie’s parents] at this moment in time,” series star KJ Apa told ComicBook.com during a set visit back in February. “He hasn’t seen her for a long time so it’s obviously really surprising when she comes in the door with Fred. The few scenes we have together are really great.”
