Ninjago, Season 4: Tournament of Elements

Jay:
[a Kabuki starts fanning too close to him] If we're gonna convince anyone, argh, we need proof. Ugh. We need to, oh, find that spell. [to the Kabuki] Would you cut it out?!

[The Kabuki is revealed to be Nya]

Nya:
Jay, it's me.

Ninja and Garmadon:
Nya?

Nya:
Lower your voices. I'm undercover. And to be completely honest, a bit out of my element. And I heard what happened to Cole. That was big of you both.

Jay:
Love is like war, Nya. Everybody gets hurt.

Kai:
Is it just you, sis?

Nya:
Dareth's also on the island.

Dareth:
[on a communication device] What up, ninja?

Nya:
And in contact with Wu via mobile base.

Kai:
If you're undercover, that means you can get close to Clouse's spellbook. All we know is that it's on page 149. I think he might have it in his quarters.

Nya:
I'll look into it. And it sounds like you have your work cut out for you too.

Jay:
How so?

Nya:
How do you think they found out about your little alliance? Someone in your circle of trust is a spy.
