Upon hearing that Judy was the one who used fox repellent on Nick, her own partner, Bogo was taken aback. "Are you sure it was Hopps?" He knew it was a stupid question but he couldn't process what he was hearing.

"I'm sure." Nick got off the bed. "Did you bring my sunglasses, sir?"

The chief handed over the glasses and was relieved once the fox's eyes were hidden. If there was one thing that interfered with his thinking, it was seeing one of his officers injured. "You picked a bad day to forget your shades, Wilde."

"Tell me about it," said the fox ruefully. "I don't think it was Judy's fault, sir. She didn't seem to recognize me."

"Start at the top."

"There isn't much to tell. I checked in with Captain Haidar and he assigned an officer to drive around with me since I'm not familiar with the area. We got a call that Judy had been sighted at an ice cream parlor." Nick's voice faltered. "When we arrived, I got out of the car and approached her, and she…" He gestured to his face. "Once I was down, she took off. Nobody's seen her since."

Bogo turned to Wiley. "Do you have anything to add?"

"No," said the coyote slowly, "but I might be able to help. I heard about the car accident Officer Hopps was involved in on our police scanner. It sounds to me like she could be suffering from amnesia, induced by a blow to the head. If that's the case, it may be possible to determine what she might do next."

"If Hopps doesn't remember her own partner, how is it possible to predict what she'll do?" asked Bogo impatiently.

The coyote looked around the emergency room. "Let's take this to my office. I think I might be able to shed some light on the situation."

Dr Wiley's office was not large and seemed even smaller with all the books it was crammed with, but he removed a number of volumes from two chairs so Nick and Bogo could sit, and perched himself on the edge of his desk. "Amnesia is a rather mysterious condition," he began. "It's extremely rare for an animal to suffer memory loss to this extent, but it's almost unheard of for memory to be permanently lost. As time goes on, the mind begins to remember."

"I don't see how that helps," said Nick. "We need to find Judy now, not wait for her to remember us."

"Of course," said the coyote. "Tell me about Officer Hopps. I read a little about her when the Night Howlers case broke. She was the first bunny on the police force, yes?"

Bogo nodded. "Valedictorian at the academy. Drove me crazy. She wanted to work the missing mammals case on her first day, hardly an appropriate assignment for a rookie."

"Where did you assign her?" asked Wiley.

"Parking duty. It seemed like a good fit. She was a political appointee of Mayor Lionheart's and I wasn't impressed by her class standing. There's a difference between being the top of your class in a controlled situation and actually working out on the street. And she wasn't from Zootopia, she came from a small farming community."

"Bunnyburrow." Nick smiled reminiscently.

Bogo said earnestly, "Hopps is a good cop, but when she graduated from the academy, she didn't know the city at all. I put her on parking duty so she could learn the streets, start dealing with the public in a relatively safe position of authority."

Wiley leaned forward. "How did she handle her assignment?"

"Not well," said Bogo dryly. "One would expect the valedictorian of the class to know police procedure. She abandoned her post to respond to a robbery and chased a suspect into Little Rodentia where she incited a scurry. I would have fired her, but Deputy Mayor Bellwether intervened."

"It seems she eventually won your respect."

"She did," replied Bogo, "but I fail to see how any of this helps to find her."

"It sounds like her first day was extremely eventful," mused Dr Wiley.

"It was," said Nick. "That was the day we met."

"Oh?" The coyote looked interested. "What can you tell me about that meeting?"

Nick hesitated and Bogo snapped, "I've already read the incident report Hopps wrote about that day, Wilde! Start talking!"

"Yes, sir. I met Judy at an ice cream parlor." He paused, then repeated very softly, "An ice cream parlor."

"You said she attacked you at an ice cream parlor," said Wiley.

The fox nodded vigorously. "And she was carrying fox repellent when I met her."

"Now we're getting somewhere." Wiley rubbed his paws together. "Are you and Officer Hopps close?"

"Very," said Nick.

The coyote raised his eyebrows. "And yet she wrote an incident report of your first meeting. That doesn't sound amicable."

"It wasn't." Nick squirmed under Bogo's baleful eye, then sighed. "When I met Judy, I was a con artist. I scammed her for a giant popsicle that I could melt down and make a lot of smaller popsicles to sell. She was furious with me and I told her off and tricked her into walking into wet cement."

"Is it fair to say she disliked you that first day?" asked Wiley.

The fox said evenly, "I think it's fair to say she hated me that first day. In fact, I think it's fair to say I went out of my way to make her hate me."

"Then we have a place to start," said the coyote. Nick and Bogo stared at him, puzzled. "Officer Hopps seems to be subconsciously back at her first day as a police officer. The ice cream parlor, the fox repellent, even injuring her partner, who on that first day was a stranger whom she came to hate. I think it very likely she'll go to the ice cream parlor where she first met you, Officer Wilde. She's trying to get back to her life." Nick and Bogo exchanged an excited look and the coyote held up a warning paw. "You must be very careful. Remember she's scared and confused and she doesn't know you as her friend and partner, only a stranger that she hates. You must act accordingly and approach her carefully, in a way that will jog her memory, not traumatize her further. I would suggest not having any police uniforms anywhere Officer Hopps would see them. As much as she prizes her career as a police officer, that first day was very painful. You will have to think of another approach."
