So Kuvira isn't targeting Republic City but the Swamp for her resources. I think Toph, even with all her greatness, can't stop the the great uniter and her army doing the thing. We might see a Toph vs Kuvira (and maybe her whole army) fight, and I'm afraid to see Toph loosing to that empress ozai. I have a feeling that Kuvira will be able to make another spirit vine 'thingy' and will succeed in getting what she needs.
What are your thoughts about this episode and speculations on the next?
