(OOC: 'Cause if Korra gets details, she'd totally offer to see if she can use waterbending to help. Then we can get into figuring out if the red rust could even infect humans. And then see if waterbending can do anything.)

[Korra's eyes widen. Her voice is immediately concerned.]

You're sick?

[Korra blinks, looks awkward, rubs the back of her neck. She frowns, her eyes downcast. She hadn't been very effective at using her powers for good lately. More like a complete failure. And she had tried to kill Tarrlok--was that good? Great, she wasn't even sure what good was anymore.]

Well...I try. I've been trained since I was four to use my powers for good, to protect my world....

[Korra's frown deepens, and she stops.]

[Korra gapes at the sword.]

Oh wow, that is so awesome! My people don't even have Sokka's sword, no clue where it is! It fell on the night of Sozin's Comet, and no one's seen it since--!

[Korra still gapes at the sword.]

Wow! How'd you get it?
