There you two are!

The villain Symmetric Al stole my jetpack, and I need your help.

I'm trying this new thing where I cut the small talk.

Very effective.

It works.

Once Symmetric Al shares the jetpack with other villains, Odd Squad is done... because flying villains... [Both] Not good!

Well, how hard could it be to get it back?

[Ms. O] Very hard.

Let me tell you what Al plans to do later today.

When Al leaves his house - with my jetpack - he'll walk through the town, all the way to the Villain's Vault.

It's a place where villains keep important things locked up.

This place is especially important to Al because he designed it.

Next, the vault owner will give Al a key.

Once the jetpack is in the vault, we'll never get it back.

Okay, so we know Al's plan, but what's ours?

Come with me.

Let's go the long way.

♪ [Otis grunts] [Olympia, whispering] What?

♪ You're building a fake vault to make Symmetric Al think he's delivering the jetpack, but really he's delivering it to us!

Yes.

You got there way faster than I thought.

I hired a special agent to explain the whole thing to you.

I guess you can leave now.

[Otis] So the real question is "How does Symmetric Al get to the fake vault?"

[Owen] I can answer that.

The moment Symmetric Al leaves his real front door, he'll enter a fake town - which we're building - that will lead him straight to our fake vault.

Hey, Owen, where should I put this cloud?

In the sky, Ozlyn.

That's why you're the boss!

Otis, I need you to find somebody to pretend to play the vault owner so Al thinks everything is fine when he gets to the vault.

On it.

What about me?

Owen, where should I put these tree branches?

On the trees.

Got it!

Maybe you can help Ozlyn out.

There are eight safety deposit boxes in the Villain's Vault.

Nine, if you count the ninth one.

Are we counting the ninth one?

Of course we are!

Problem is we don't know which one is Symmetric Al's, so we don't know which key to give him.

Why don't we make all the keys and let him choose himself?

Looks like we've got a key expert here.

Uh, a what?

I called you a key expert.

I mean it in the nicest way possible.

This is Agent Oxley.

He makes the keys.

[softly] But it takes him forever to make one.

Key-making is an art and not to be rushed.

We're only going to get one key out of him, so we need to guess which box Symmetric Al is going to pick.

Maybe we don't have to guess.

Symmetric Al would love this star, heart, and circle because they're symmetrical.

Symmetrical objects are the same on both sides of the line of symmetry.

This side is the same as this side.

So we just need to figure out which numbers are symmetrical and make keys for those boxes.

This is the vertical line of symmetry - "vertical" because it goes up and down through the middle of the numbers.

But look at number eight!

[Ozlyn] It's the same on both sides of the vertical line.

It's symmetrical!

And since Symmetric Al only likes symmetrical things, that must be the number of his safety deposit box.

Hear that, Oxley?

You only need to make a key for box number eight.

Way to go, key expert.

You did it.

As thanks, I'd like you to have my grandfather's golden jacket.

[Olympia] Oh... okay.

Hmm...

Thank you.

That's exactly what he would have said!

Hm!
