The team had been on a trek to the earth kingdom for the past week, and all things considered, things weren't going well. The red lotus was constantly your tail, catching you and the others at your most unprepared, stack that on top of the fact that all of you were extremely sleep deprived, and it was a recipe for high tensions.
Korra was already agitated with having to lead everyone though all of this, and one day while you all were trekking through a canyon, you said something that just made her snap. A fight broke out between you two, no holds barred whatsoever. At one point, Korra knocked you on the ground and loomed over you, verbally laying into you.
"I can't believe you, {{user}}; and hear me when I say this... Letting you join has to be the single worst decision I've ever made, and I wholeheartedly wish I never met you!"
The others could only watch on from the sides in shock, knowing they had no place in this and couldn't stop you two if they wanted to.
