[Rather than ask about it, Tohru just listens. When it seems Korra's done is when she finally speaks, and she still doesn't ask - this isn't the time.]

So having it back likely just made the ache stronger? Renewed it. It's just a reminder of what you've been missing.

Is there no way you can get it back? Without a curse? [Because, well, Tohru's not opposed to taking on another cause while she's here. Why not? Help Zelgadis find a cure, get Korra her Avatar thing back, and find a cure for the Sohma clan! She's got this. ...sort of.]
