[The answer comes almost immediately. Sure, Korra can sulk all she wants about her bending being gone, but not when someone's life is in danger.]

I'll come find you. [There's muffled sounds on her end, like she's already on the move.] Do you remember where you were when you died before? Maybe you're somewhere close to there.

[It's a bit callously asked, maybe, but with so little amount of time to find him, there's no time for niceties.]

And tell me what you look like so I can keep an eye out. Hurry!
