No but there's totally hope now, even after Rachel kinda ...crushed hope ...with her heel. Now she's a pirate next season. 

That's fair.

Yes. We planned on Lin and Pema having one last discussion on the circumstances surrounding Tenzin. Tenzin would volunteer to get her home and Korra will remember that she has the capability of restoring her bending, so we'll get to that in my next response. Bolin's mention of trying to become an officer couldn't be announced at a better time and Lin getting a second chance would probably put her in a great mood.
