With things settling down and less chaos happening, the villagers started getting their courage back to head outdoors again and speak with their neighbors. They were all keeping an eye out for any suspicious activity. They began whispering their suspicions to each other. Punchy is always late. Tipper is always early. Kapp'n is eating turnips.
"Wait, what? Kapp'n is eating turnips?" asked Nana," I thought his favorite food was cucumbers."
The villagers all turned their eyes on Kapp'n and
pixelated focused on him.
"Where'd you get the turnips?" they asked.
"Uhh, from old sow Joan," Kapp'n answered nervously.
"No one has seen Joan for over a week. Those should be rotten," replied Hamlet.
"Oh, my wee radish knows something about turnips, does he?" beamed Kapp'n. Then his face fell in realization that he just blew his cover.
"That's not Kapp'n! That's Joan!" exclaimed Tipper.
"Uh-oh. Time to go, kiddo," said Joan and she ran off to the dock and hopped in Kapp'n's boat. The villagers rushed to the dock behind her but were too late to catch her. Joan started heading southeast but remembered the shark infested waters that killed Eugene or Leif or Pokepal148 or whatever his name was and turned southwest instead. Unfortunately for Joan, she ended up sailing into the spot Crazy Redd threw
Keaton Tortimer Crimm whatever his name was into the sea with those cement shoes and the propeller hit the body and jammed up. A further final indignity for the former mayor. With the motor now out of commission, Joan could only sit helplessly in the boat as it slowly drifted back to shore and the crowd of angry villagers awaiting her.
Dragging her out of the boat, they pushed her up against the Cliffside and started asking her all kinds of questions. Why was she hiding? Why did she run? Why is she trying to push turnips on people? Why did the Stock market crash causing people to lose a ton of bells? Why is she the only one who can sell turnips and set the price?
While this inquisition was occurring, some of Tortimer's body washed ashore. The villagers were horrified. Joan must have killed Tortimer with the boat while he was diving, they charged.
"No! You got it all wrong! I didn't kill Tortimer. That was Crazy Redd," screamed Joan in protest.
"Crazy Redd!" exclaimed Porter, "What does he have to do with anything?"
Joan suddenly realized the mistake she made my protesting her innocence. Under great duress, she revealed how she had joined up with Crazy Redd and
Antonio Katrina to help eliminate Tom Nook and his economic empire so that they could then set up shop and rule the Shangri-La market. Joan further named Saharah and Grams as co-conspirators also. At last, the existence of the Black Market Foxes mafia was laid bare before the villagers. They weren't just facing the Nook clan, they also had these opportunistic flim-flam salesmen to contend with as well.
"Tortimer ran Crazy Redd and his counterfeiting operations out of here years ago. We don't want him back," declared Kicks, "75% of the time, he sells you junk but still keeps all your money and refuses to refund or reimburse you back!"
"Sort of like Joan's turnips," sneered Digby. He then picked up one of the many thousands of turnips Joan had stored in the back of Kapp'n's boat and chucked it at Joan. "Here, here," agreed the crowd and then they also started grabbing turnips and tossing them at Joan. This is for the 45 bells I had to sell my 99 bell turnips for, yelled one villager. This is for the time I forgot which day I last went into the village and ended up choosing the wrong one thus spoiling my turnips, exclaimed another villager with the power to time travel that apparently raised no interest with anyone else.
Thus, they pelted Joan with her own turnips in anger until she died. Satisfied at having eliminated another source of evil in the village, the crowd dispersed and went to their homes.

Crazy Redd, however, upset at the fact that his operation was exposed and seeing the bloodlust from the villagers and their treatment of Joan decided he'd best not risk being seen at the moment and went to his hideout to lay low until he could further act at a better time.
The next day, the villagers awoke with a renewed sense of purpose.
