To be fair, Jug's pulse could have been weak and/or irregular--even on a healthy not bonked by a rock person who isn't collapsed in a dark wooded area, a pulse can be hard to find. And Archie did give him a fireman's carry up to the med van!
This honestly summed up a lot better than I thought it would have, considering. But? Questions.
1) Why the hell hasn't four missing students been a bigger scandal than it's been? FOUR? At a richie rich school for spoiled progeny of people very very VERY used to getting their way? I get the entire point was to be perfect murders, but none of them turned up murdered or even dead--they simply vanished. What red blooded rich, connected, willing to fake test scores/slap their kid onto a rowing machine for phony photo ops parent isn't going to raise Caine in every corner of the state Riverdale is in and get the place shut down???
2) Dupont was depending on a lot more fellow psychos keeping his slaying tendencies secret than Betty et al ever had to during this fever dream, and for decades, not a few weeks. Why the hell hadn't any of the previous ghostwriters demanded blackmail, or any of his students who didn't get the contract turn him in out of rage?
3) Charles, you are one patient man, but not as patient as your lover, Chic, who is rotting in a jail cell having been framed for the murder ALICE committed and FP helped hide, with the assistance of our favorite duo! Why the heck did the writers bring this thread into play at all? It has gone NOWHERE.
4) And seriously, JOHNATHAN. A Black student is murdered, murdered, by his fellow Stonies and people care less than...about anything else. He may have been in on most of it, obviously, but, what, was the writers' idea to make up for his complete lack of character or agency and his off-screen, footnote death by letting him grow a dubious conscience that he never once got to voice from his own mouth?
Things I did like:
Betty's little spin towards the door as soon as Jug said "locked room mystery." Which, by the by? That's not a locked room mystery--the term refers to a murder that seems to be unsolvable due to the apparent lack of ways for the murder to commit the crime and escape (that is, the victim being murdered in a room locked from the inside and being found alone), not the rich tradition of gathering all the suspects in the parlor and recapping the crime.
Brett getting the pudding beaten out of his stupid face. Nice how Joan had an ambassador daddy and Donna was all self-confident while Brett relied on gross videos and bravado. Serves you right, asshead.
Jughead's neat row of forehead stitches, which don't make much sense since Joan hit him in the BACK OF THE HEAD.
That actually was a win for the writers--the fact that this driven lunatic could pour so much of her life into this sweet revenge and at the very last minute end up with nothing. Really, no prison could be worse for her particular personality, and Betty knew it.
