Garfield Elementary School was four blocks away from the Rockwaller house, so it didn't take Kim and Bonnie very long to reach the building. It was still early and classes hadn't started yet, so the girls would have a chance to talk with the teachers and staff before the students started to arrive. The first step would be stopping in the office to talk to the principal, Mrs. Lawson. She had only become principal a few years ago, so Bonnie didn't know her well.

As they entered the office, Mrs. Lawson was clearly quite surprised. She was used to dealing with grade-schoolers, not teenagers—particularly not the world-famous Kim Possible. "Can I help you?"

"Mrs. Lawson, I'm Johnny Rockwaller's older sister," Bonnie told her. "Kim Possible and I are trying to find him and we need any information you can give us about where he was yesterday."

"Oh yes, absolutely. I talked to the police yesterday, and all of us are worried about him." Mrs. Lawson sighed. "There's really not much I personally know. I don't see the kids much during the day unless they get in trouble, and Johnny's a good kid. But I'll give you both visitor's passes so you can go talk to his teachers and classmates. They'll be much better sources of information than I will."

"Will do. Thank you so much!" Bonnie turned to Kim. "Follow me. I'll take you to Mrs. Baker's classroom."

"Lead the way. I'm guessing she's his second-grade teacher?"

Bonnie nodded as the girls began leaving the office. "I actually had her for second grade myself, back when she was Miss Murphy. She's really nice and Johnny likes her." She pointed to a room down the hallway. "There's her classroom. It's Room 108."

The two girls headed inside the classroom and saw a blonde woman in her thirties preparing a lesson. Looking up, she instantly recognized her former student. "Oh, hello Bonnie. Is there any word about your brother? Poor thing."

Bonnie shook her head. "No," she sadly admitted. "But Kim Possible's helping us look for him. That's why we're here."

Kim smiled politely. "Hi. I'm trying to find out as much as I can about Johnny's whereabouts before he disappeared. Bonnie said you're his teacher, so you would have been one of the last people to see him. Can you walk me through the events of that day and where Johnny was?"

"Oh, certainly. I don't mind at all." Mrs. Baker picked up her workbook. "The students start entering the classroom at 8:25 and the bell rings at 8:30. Johnny came in with the other students and was in his seat when class started, so there was nothing out of the ordinary there. After I took attendance, I gave the class their list of spelling words for this week, and they worked on phonics for a while. Then I read the next chapter of Aliens for Breakfast, and the class did a worksheet about the events of the story. At 10:15 we switched focus to geography, and talked about the difference between city and country. That was about forty-five minutes. Then the class went to lunch at 11 and recess after that at 11:30. Johnny went to the cafeteria with his classmates and came back from recess on time at 12:00."

"Bonnie mentioned something about a math test that Johnny was worried about," Kim said. "When was that test?"

"It was right at noon, once the class was back from recess. He did seem a little nervous about it, since math is a weak point for him and the test was fairly challenging. But I didn't notice anything out of the ordinary. Lots of kids get nerves before a big test, and Johnny took it just like the other students." Mrs. Baker picked up a worksheet and handed it to Bonnie. "Actually, here's his test. I graded them last night, and you can see he did well. He got a B+."

Bonnie bit her lip. She wanted to be happy that he had done well, but that didn't mean anything if he was missing. "What happened after the test?" she asked.

"We focused on math until 1:15, and then switched to science. We discussed the water cycle until about 2, and then the kids went to art class for the rest of the day."

"Art class?" Kim asked.

"Yes. Our class usually has its specials at the end of the day, and art is on Monday."

"Then it sounds like we need to talk to the art teacher. Thanks for your help, Mrs. Baker." Kim turned to Bonnie. "Where's the art room?"

Bonnie led her upstairs and down a hall to the art room. The teacher, Mrs. Thompson, had also been there when Bonnie was a student, so she recognized Bonnie as well. "Bonnie, what brings you here?" she asked in surprise.

"We're looking for Johnny and are trying to figure out what happened to him yesterday," Bonnie said. "Mrs. Baker said that her class had art before school let out yesterday, so that would mean this was the last place Johnny was before he disappeared. Can you tell us anything about what happened yesterday?"

"Oh, absolutely. Well, since it's October now we're doing Halloween projects, and right now the second graders are working on creepy paintings. Actually, there was an issue yesterday between Johnny and another student, Chris Jones."

Bonnie immediately made a face, prompting Kim to look at her in confusion. "Who's Chris Jones?"

"A bully. We hear about him a lot. He's the meanest kid in second grade, and since he was held back a year he's also the biggest. Johnny's afraid of him." She turned to the teacher. "What happened, exactly?"

"Chris decided to be a troublemaker and deliberately spilled orange paint on Johnny's Frankenstein picture. He was sent to the office, but Johnny was still pretty upset about it. I don't blame him. He had worked on that painting for two weeks, and now it's pretty messed up."

Bonnie looked deep in thought. "What happened when class was dismissed? Which group did Johnny leave with?"

"As I recall, he went with the walkers."

A look of understanding came over Bonnie's face. "Thank you very much, Mrs. Thompson," she said and quickly left, pulling a very confused Kim behind her.

"Bonnie, hang on a second. What does that have to do with anything?"

"Johnny normally rides the school bus home, but yesterday he never got on it. Well, Chris Jones also rides his bus," Bonnie explained. "This explains why he didn't take the bus. He was having problems with the bully and he didn't want to be hassled on the way home. So he tried to walk instead."

Kim nodded. One part of the mystery was indeed solved. But there was still another, much more important—and much more frightening—question. What had happened to Johnny on his way home?
