Jughead unraveled the season-long mystery for the Stonewall preppies.
(I think?)
That honestly might be the most messed up thing these kids have done.

And ultimately, it was Hermosa who brought them the final piece of the puzzle more on that later.
(No way this speech only took half an hour.)
Why would he do that?
Because Moose was going to get murdered and Chipping was trying to save his life.
This brings us to the Baxter Brothers writing competition part of the story/season.
Bughead linked each of the missing Stonewall Four to the years that new ghostwriters joined the Baxter Brothers franchise.
And that brings us back to Moose.
Chipping invited Moose to Stonewall Prep to be the next victim to be killed by the next chosen ghostwriter.
It was Jonathan’s job to check that Jug was dead.
He clearly failed, which is why he’s not in this room right now.
Then, they placed the rock in Betty’s hand and pointed Archie and Veronica in her direction.
Even half-head, Jughead had a plan.
And each one of them asked for a lawyer.
Ever since, he’s been collecting evidence against DuPont.
Further proof Charles isn’t a good FBI agent?
He didn’t stop DuPont despite the man obviously positioning himself closer and closer to a window.
And that’s where Hermosa’s very important piece of information comes into play.
It seems Donna’s grandmother was one of the original classmates that DuPont killed to cover up the truth.
Furthermore, DuPont stole the character of Tracy True from Donna’s grandmother.
So not only does that give Donna a motive, but it links everything back to her.
“Play nice from now on,” Betty tells her.
“I’ll be keeping an eye on you.”
Then, she calls Betty out on her feelings toward Archie.
When Betty says it was all pretend, she says, “It looked real to me.”
But don’t worry, Betty.
Your secret’s safe with Cheryl.
With Jughead accepted back to Riverdale High, the core four meet at Pop’s.
Well, that and Kevin’s variety show.
Do I find those answers satisfying?
