DuckTales, Season 1

Dewey:
So where's the Spear of Selene, Selene?

Selene:
What spear?

Dewey:
The one Della took from your garden.

Selene:
You mean the Sphere of Selene?

Dewey:
Why does no one get what I'm saying? The Spear of Selene!

Selene:
I've never had a spear. Do you mean the Sword of Selene? That's down the hall-

Dewey:
No! The Spear of Selene! The one my mom took! The one that's our only clue to finding her!

Selene:
Ah, you're Della's kid! I shoulda realized, you're just like her. I'm sorry, I haven't seen her in years, and I don't know what the Spear of Selene is.

Dewey:
So we're back to "she stole Scrooge's spear and betrayed the family" then. Great.

Selene:
What? No way. She loved her family more than anything in the world. Oh, Della wasn't just a good person, she was the greatest, and she made everyone around her better.

Webby:
Maybe the spear isn't an artifact. Maybe it's something else.

Selene:
Your mom did love a good mystery. [gives Dewey her Sphere] Here. It's not a spear, but it is a treasure even Della never found. Don't give up, young duck. Your mother never did.
