[So the whole "fight for an arbitrary side for an arbitrary reason" has never sat well with her - it's why she's switched sides in the first place, after all. But never one to do things by halves, that just means that tonight Korra is struck by a sudden Urge to Unite, and she's just marching out towards the border and crossing the border towards the Dragons of Earth side.
Hey, diplomacy! Or something. She's not about to hide or sneak around. She's ready to get the two sides working together. Why fight, after all? She. hasn't thought out a concrete plan but whatever.
Brilliant or foolhardy? Who knows! Feel free to join her. Or stop her. Or stare at the weirdo walking over into your territory.]
