Chapter 6:

The gang were at Shaggy's house. "Collins has to be our guy," says Fred.

"Easy," says Velma, "just because he has an interest in Arthurian legends, doesn't mean he's the Black Knight! We have to be sure!"

"What if we were to trap him," Daphne suggests.

"That could work," says Fred, "here's the plan!"

...

The gang exit. "Where you kids off to," asks Mr. Byrne.

"Oh, we're just going to expose our teacher of being a possible criminal," says Shaggy.

"Don't go around telling everyone," says Velma.

"Don't worry, your secret's safe with me," says Mr. Byrne, "have fun!" The gang then leaves.

...

The gang were at the museum. "So, how are we going to lead him in our trap," asks Daphne.

"We just need bait," says Fred, "when we were running from that knight, I noticed Shaggy and Scooby were faster than you and me!"

"That's why I'm so skinny despite eating so much," says Shaggy.

"Sorry, Guys, but you're going to have to be bait," says Fred.

"Are you crazy," asks Shaggy, "you want us to get that nutty knight to chase us?"

"How are we going to convince them," asks Velma.

"I might have an idea," says Daphne, "you know how my dad's a businessman? Well, his business is making dog treats! Scooby, would you like one?" She holds it out. Scooby sniffs it and takes it.

"That might work on Scooby," says Shaggy, "but it won't work on me!"

"Shaggy, everyone knows you eat dog treats," says Daphne.

"Like, I like it better when people ignored me," says Shaggy. He then takes one.

...

Shaggy and Scooby were looking for the knight. They then saw him and ran and the knight followed. "Wait," says the knight. Shaggy and Scooby then, successfully, lead the knight into the trap! Fred unmasks him and they see it's Prof. Collins. "What's going—"

"We got you know, Black Knight," says Fred.

"No, you don't understand," says Prof. Collins, "someone kidnapped me and forced me to wear this armor!"

...

Prof. Collins was being taken in by the Sheriff.

"What about Prof. Hyde White," asks Daphne.

"We searched that museum," says Sheriff Buzby, "couldn't find him!" Daphne then thinks about it…

...

Daphne returns to the museum and starts searching. "Daphne Blake," says Mr. Jordan, "was there something else?"

"Actually, yes," says Daphne, "there's still a missing professor and… wait, what are you doing here, Mr. Jordan?"

"Why don't you ask my partner," asks Mr. Jordan.

Then the Black Knight grabs Daphne…
