There is a line/quote I'm trying to remember, but I'm not even sure that it's from TotA. I thought it might be Jade who said it, but I'm not sure.
Here's what I'm remembering.

Unknown person: Only if you get on your knees and beg me.
Jade: Certainly. *kneels*
Unknown person: Have you no pride?
Jade: Oh, none such that would be affected by something like this, I can assure you.
Unknown person: *annoyed*

If it was from TotA, what exactly was the quote?

I think the unknown person is Emperor Peony. I remember doing that event earlier in the game. Hilarious scene. xD

Oh, so it was from the game? Then if someone remembers the exact quote, post it here please. Can't find any game script on Gamefaqs.

~Edit~

I think I found it.

Luke: Oh, I'm hurt, gramps. Is that all I'm good for? And didn't anyone ever teach you to bow your head in respect when asking someone for a favor?
Tear: Don't act like that, Luke. You don't want a war, either, do you?
Luke: Would you shut up already? ...Well?
Jade: *Sigh*

Jade bows to one knee.

Marco: Commander!
Jade: Master Luke, please grant us your aid.
Luke: Man, do you have any pride?
Jade: None so cheap as to be shaken by something as petty as this, sir.
Luke: ...Tch. Fine, whatever. You just need me to talk to my uncle, right?

Jade gets up.

Jade: You have my deepest gratitude. Now by your leave, Master Luke, I must attend to other matters.
Luke: Stop calling me "Master". Coming from you, it's just...wrong.
Jade: As you wish, "Master" Luke.

That's way early in the game, isn't it? When Luke is still a spoiled brat?

Yeah, I think it's when they were onboard the Tartarus early in the game.

That's from back when you were 'captured' by the Tartarus after the Cheagle Forest, isn't it? Really early in the game. =o

Spoiled and whiny!Luke is so friggin' awesome.

Forgot about that one - classic - on the mention of Peony got confused with the scene when you obtain the Lost Celesti - another good one if memory serves.
