Fred, Everyone and others in “Unfinished Business”

Now, let's see who this ghostly monk really is. (unmasks Serra's face)

George Avocados? (The crowd is surprised)

That's Avoc--ah. Oh, forget it. That's right. It is me.

Yes! Finally! I knew you'd be the villain eventually.

All right, you got me. And I suppose you're wondering, after so many prior misdirects, why now.

Daphne

Actually, no. Not really. We kind of always knew you were evil.

Hmmph! Okay, fine. Then my tale should not surprise. It all began after I failed in politics. I had no choice but to go into the family business: Farming avocados. Everything was going so well until you mystery brats blew up my crops. I then tried my hand at fortune telling. But when that endeavor failed... I fell back on the Avocados legacy of stealing other people's things. I located the Avocados diamond, stolen by my father. Turns out, it actually was disguised as a door knob, not on a door in Crystal Cove, but on a door at the Burlington Library. When I found out it was among the artifacts sent here for the production. I took a job as a janitor. I needed everyone to stay clear of the basement to give me time to look. I hid the body of Friar Serra in a closet and assumed his identity. Knowing this town's gullibility, I knew a ghost story would give me room to hunt. And I would have succeeded, TOO, if it weren't for Vincent van Ghoul.

Moi?

Velma

So the brown residue that was left behind...

That's right. Guacamole! Now, I want my diamond! (tries to grab the diamond staff but Daphne grabbed it)

Daphne

Let me see something. This crystal is the diamond!

Shaggy

But, like, hold on. If you were the friar, how did you appear at the rehearsals?

I didn't. I assumed that was you meddling kids trying to trick me into revealing myself.

Huh?
