There's so much jaw-dropping suspension of disbelief in this premiere episode of RIVERDALE's third season, you'd almost think it was based on a comic book.
Archie (KJ APA) has been on trial all summer long for a murder he did not commit. Of course, he was there when it happened, he told nobody about it, and he knew who did it, but other than that he was innocent. And sure, he really did organize two vigilante gangs and physically assault an injured, bedridden teenager, but at heart he's just the boy next door.
Archie's defense lawyer really has his back on this one. She's his mother, Mary Andrews (MOLLY RINGWALD). Normally I'd have thought a lawyer would have to recuse herself from representing a close family member, but I'll confess I could be wrong on that, since I'm not a lawyer but just a casual viewer of proceedings. And she puts up a pretty good defense, too, given all the rational arguments made by the prosecution.
