(a Celtic accent would be good, but you may use whatever accent you are most comfortable with, so long as he has one...Avatar prides itself on being inclusive and I want this role to help reflect that...he is also older, so as long as you can sound like someone old with an accent, you are in the running; this particular line should reflect that he is aware of Ozai's strong firebending capabilities and so is doubting that Sonic will survive his bad burns from fighting the Firelord, but is relieved to see that not all the water benders had been killed, and so by extension...he is glad to see Katara) I thought that the art of water bending had been lost completely, my dear. I am glad to see that is not the case. Tell me, young lady...how long have you known this young man?

(remembers seeing Eggman briefly, so in this line he should sound somewhat reflective and somewhat vexed, because Eggman kind of made fun of him for his age...if you want, I can arrange for a call on Discord and we can do this as a bonus animation, but it won't be included in the main story) A red lab coat...yes, I remember seeing someone like that in the palace a few days ago. He's not there now, but he left last night, cackling up quite the storm. (glares and looks at his wife, who is with him, a bit suspicious of the exchange now) We asked him what was so funny, but he would not elaborate and left without so much as a word. He had two others with him. One was a...blue machine-like being and the other was a dog-like being with a two-toned tail. That's the best that I can do to describe them. Why, is that relevant?
