(Back to Shaggy)

Daphne: Shaggy, are you alright?

Shaggy: She looks familiar somehow. But how?

Fred: What do you mean?

Shaggy: When she pushed me, she dropped this ring. I think she must've got it from somewhere.

Velma: Let me see.

(Velma takes a look at the ring)

Fred: Well?

Velma: I think it's a wedding ring. But i don't know who did she married to.

Fred: Well looks like it's another mystery on about who she is.

The Mysterious Girl revealed
(The Girl sees Shaggy and Scooby running and sees that Shaggy has her ring)

A Girl: You! Is that my ring?

Shaggy: Yeah, why?

A Girl: That's my wedding ring moron! Now Lorcan and my mom are going to be so mad that I almost dropped it when I had to use the toilet!

Shaggy: Hey, who are you calling a moron for?! Wait.

Scooby: Lorcan? As in Lorcan Darcy?

A Girl: Yeah, she's my baby sister. We're both both on our mom's side, she's black and our dad's white.

Shaggy: Wait, if your sister is Lorcan, are you...?

A Girl: Allow me to introduce myself, I'm Cillian Darcy of the second dimension. Lorcan's older sister, Jack, Melissa, Nightmare and Kino's half-sister, Molly Williams' step-daughter, Maisie and Jack Darcy's eldest daughter and Molly Mayne's sister-in-law. Lorcan that good-for-nothing-stupid-little...!

Shaggy: Who's Molly Mayne?

Cillian: Lorcan's wife! She's a lesbian!

Scooby: Wait, Cillian? Well, that's just freaky.

Cillian: Yes, what do you think she is?!

Shaggy: Okay, okay, don't be a grouchy. What are you doing here?

Cillian: My little sister's dimensional portal! Thanks to her, I should've gone to the bathroom before i came here.

Shaggy: Okay, listen! We need your help. Our friends got kidnapped by this mysterious Shadow King.
