Cold feet warm heart
or
Why firebenders are great.
"Ooooohhhhhhhh, you are so warm!"
"Gah! Your feet, they're like ice!"
"Deal with it, Fire Lord."
"Katara, what the hell is this? It's been less than three years since the war ended and you want to put a Fire Nation base at the South Pole?"
"Sokka, it's not a military base. We've been over this. They will have no weapons. That's a key part of the deal, you've read the agreement, and you know this."
"Yes, no weapons, I know, other than being fire benders!! Dad will never accept this and you know it, not everyone is ready to make nice with the Fire Nation"
-Elsewhere-
"Lady Ursa, may I have this dance?"
"Why Chief Hakoda, whatever will our children think?"
"They will think 'who is that astoundingly beautiful woman he is dancing with? She is far too good for him.'"
Ursa doubted it was true (except for Zuko with the second part) but couldn't help but giggle and be held as they danced.
-Back to Katara and Sokka-
"Zuko's planning something, or it might be Azula, that'd be it. Zuko's too dumb to do this alone. Azula put him up to this!"
Katara wanted to hit her brother, but that would be unseemly for a Fire Lady...
She did it anyway.
"I told you to stop picking on Zuko." That was her hobby; there wasn't any room for amateurs. "If you must know, it was my idea."
"………"
"Stop it, or your face will freeze that way. Look you don't understand what it's like." She let out a huge sigh. "You need to sleep with one to see what I mean…"
"KATARA!"
"It's not like that, well actually it sort of is, I mean when they say they rise with the sun they're-"
"ENOUGH! I don't want to hear this, Katara; there is no way this is going to happen!"
"They don't get cold, Sokka."
It may seem strange, but this was enough to derail Sokka's train of thought. Both Katara and Sokka came from Polar Regions, where maintaining body heat was more than just for comfort, it was survival.
"Well, they do get cold, but then they just focus a bit and they're all warm again"
"I'm not sure I see how this helps us."
"Do I have to spell it out for you? Firebenders are like walking hot water bottles. Hug one and see."
-Later-
Ty lee was in heaven, the cutie had just hugged her, and she didn't even have to paralyze him this time!
"Hrmm, Katara said Fire Benders were warm."
"M'not a bender." Ty Lee sighed dreamily "So when do you want to get married? -Ouch- Hey!"
Sokka was walking purposefully towards Azula.
FWOOOOSSHH!
"Don't even think about it."
