Later, Michael, Alex, Sabrina, and her brothers were at the stables, ready for flying derby tryout practice. Cora, Kerry, and their friends met up with the riders.

Kerry wished her brother and cousins good luck, but Cora wasn't so sure if she herself was excited for the tryout race. Just then, Prince Robin showed up. Cora, Saffron, and Fiona were surprised, and they were excited to see Robin.

"Prince Robin, nice to see you," Cora smiled dreamily.

"What brings you here?" Saffron asked.

"I'm just here to support Lady Sabrina," Robin replied.

Cora's, Saffron's, and Fiona's smiles dropped. They sadly watched as Robin walked over to Sabrina.

"Sabrina, I see you're trying out for the flying derby team," Robin smiled.

"Yes, I am," Sabrina smiled back.

Eric, Bryan, Michael, and Alex watched as Sabrina and Robin talked. Just then, the flying derby coach showed up and called, "Okay, riders! Let's huddle up."

Sabrina and the boys huddled up. Robin went to watch practice with the other girls. Cora, Saffron, and Fiona were green with envy. They had no idea what Robin saw in Sabrina.

"I don't get it, Cora," Saffron muttered. "What does Robin see in Sabrina?"

"I wish I knew," Cora replied. She saw that someone threw a banana peel in the trash—and that gave her a very nasty idea.

Meanwhile, during practice, the riders were told by their coach, Sir Andre, that there would be three winners. The first two riders to cross the finish line will be on the team, and the third will be the backup rider. Sabrina and the boys wondered which three will cross the finish line.

Sabrina and the boys each got on a horse and took off into the sky. Sabrina was having a lot of fun riding. Robin thought she was a really good rider and watched as Sabrina rode on her flying horse, Lavender.

Cora and her friends couldn't stand to see Robin staring at Sabrina riding. Sabrina made it through the race course and was about to land near Robin.

Suddenly, Cora threw the banana peel in Sabrina's direction. When Lavender landed, she slipped on the banana peel and fell. Sabrina fell out of the saddle and landed hard. Kerry, her friends, and the boys were shocked. Cora, Saffron, and Fiona tried to hold back their laughter.

The riders ran over to Sabrina, who was fighting back tears.

"Sabrina, are you okay?" Michael asked.

Sabrina couldn't say anything without crying, so she lifted her sleeve, showing a scrape. It really broke Eric's and Bryan's hearts to see their sister in this condition. It wouldn't be easy to tell their parents.

Sir Andre saw Sabrina's plight, and he had also seen what Cora and her friends had done. "Can someone take Sabrina to the nurse?" he asked. He turned to Cora and her friends and rebuked, "You girls are coming with me."

Sabrina was taken to the nurse's office. The nurse took care of Sabrina's scrape. It didn't hurt anymore, but Sabrina was embarrassed. Eric and Bryan were sad to see Sabrina like this. This first day at Royal Prep was really hard for all three of them.
