"There it is!" Judy said. She could see the ZPD offices through the exit doors of the museum.

"Judy! Judy!" a voice called.

Nick and Judy came up the stairs from the subway and raced through the empty Natural History Museum on their way to the ZPD. All around them were statues and exhibits telling about the history of the evolution of Zootopia.

"Mayor Bellwether!" Judy said. "We found out what's happening. Someone's darting predators with a serum -- that's what's making them go savage."

They stopped and turned to see Bellwether standing behind them with two sheep cops.

"Thank you, ma'am… How did you know where to find us?" asked Judy.

"I am so proud of you, Judy. You did such a super job," said Bellwether, applauding.

"I'll go ahead and take that case now," said Bellwether.

Something about the way Bellwether was acting made Judy suspicious. "You know what? I think Nick and I will just take this to the ZPD…"

Judy turned to go, but the sheep blocked their way. Why wouldn't Bellwether let them leave? All of a sudden, it became crystal clear to Judy. Bellwether was the one behind this from the very beginning! That was why she had known where they would be. Judy signaled to Nick and they dashed off down a corridor as Bellwether shouted, "Get them!"

"Take the case," Judy whispered passing it to Nick.

"Just… we'll think of something," said Nick.

"Come on out, Judy!" called Bellwether.

"Pass," she said.

"Get it to Bogo."

"I can't walk," said Judy.

While she and Nick were running as fast as they could toward the police department, Judy glanced over her shoulder. She didn't see the woolly mammoth tusk sticking out in front of her, and ran right into it. Judy screamed in pain as the tusk slashed her leg and knocked her off her feet.

"Carrots!" shouted Nick.

"I'm not going to leave you behind. That's not happening," said Nick.

Nick rushed to her. Her leg was bleeding badly. He carried her behind a pillar. "I got you, come here. Okay, but just relax." A few blueberries rolled out from Nick's pocket. "Blueberry?" he asked, offering one to Judy.

"We're on the same team, Judy!" said Bellwether, trying to get Judy to surrender. "Underestimated. Underappreciated," she went on. "Aren't you sick of it? Predators -- they may be strong and loud, but prey outnumber predators ten to one. Think about it: ninety percent of the population, united against a common enemy. We'll be unstoppable."

Bellwether spotted the shadow of long rabbit ears against the wall and gestured to the sheep. They pounced, but it was just a mummified jackalope. Judy and Nick made a run for it.

"Over there!" Bellwether shouted.

Whack! A sheep tackled them, knocking the case out of Nick's grip and sending them both into a sunken diorama. Bellwether looked over the edge from above.

"What are you going to do?" asked Judy. "Kill me?"

"Of course not… he is," said Bellwether, gesturing to Nick. She took the dart gun out of the case and aimed at Nick. Thwick! The dart sank into Nick's skin.

"No! Nick!" Judy yelled.

"Yes, police!" Bellwether said into the phone. "There's a savage fox in the Natural History Museum. Officer Hopps is down! Please hurry!"

Nick started to shake and crouched over as Bellwether dialed her phone.

Judy searched for a way out of the diorama, but there was nowhere to go. Nick, now on all fours, looked like a wild animal. "No. Nick," said Judy. "Don't do this. Fight it."

"Oh, but he can't help it, can he?" said Bellwether. "Since preds are just biologically predisposed to be savages."

Bellwether looked on, completely confused.

"All right, you know, you're milking it. Besides, I think we got it, I think we got it. We got it up there, thank you, yakety yak -- you laid it all out beautifully," Nick said.

Nick stood up and helped Judy to her feet.

Nick growled as he cornered Judy.

"Bye-bye, bunny," said Bellwether.

"Gosh, think of the headline: 'Hero Cop Killed by Savage Fox,'" said Bellwether, pleased with herself.

Nick stalked Judy like a predator about to attack as she helplessly tried to limp away.

"Fear always works," said Bellwether. "And I'll dart every predator in Zootopia to keep it that way."

"Blood, blood, blood!" shouted Judy. "And death."

"Pretty much," said Bellwether.

"What?" Bellwether said, trying to figure out what was going on.

Nick lunged at Judy. Bellwether smiled.

"It won't work," said Judy.

Nick held up the ball of serum, then gestured to the gun. "Yeah," he said. "Oh, are you looking for the serum? Well, it's right here."

"So that's it? Prey fears predator, and you stay in power?" asked Judy.

"They are delicious. You should try some."

Nick licked his fingers.

"I framed Lionheart, I can frame you! It's my word against yours!" she yelled angrily.

"What you've got in the weapon there -- those are blueberries. From my family's farm," said Judy.

Bellwether looked down to see a blueberry in the chamber of the dart gun.

Nick pressed a button on the pen, and Bellwether's voice played back: "And I'll dart every predator in Zootopia to keep it that way…"

"Oh, yeah, actually…," Judy started.

Nick held the carrot pen up high into the air so that Bellwether could see it.

"… it's your word against yours," said Judy.

Judy and Nick looked at one another and smiled. "It's called a hustle, sweetheart," they said together.
