I'm Korra. [What should she say, she wonders. The new brother's temper hasn't escaped her notice, for one, and Korra gets the feeling she might not be out of the woods yet, no matter how much Al vouches for her. Is that what Tenzin, Lin, and the others saw when I first got to Republic City? Yeesh.

In the end, it's easier to go with the truth. Korra smiles in Al's direction.]

I got lost out here and your brother was helping me out. Sorry about keeping him. [She adds a second later.] We were just heading back to Briggs now.
