Mako:[to Korra] You're the most loyal, brave, and selfless person I've ever known.
Asami:I betrayed my own multimillionaire father, the only family I have left, to stay loyal to you. We live in a sewer now, right after I found out you were being disloyal to me.
Bolin:I tried to be brave and make us money to enter a tournament to continue to pursue our dream, was kidnapped by a gang then kidnapped by the Equalists and almost lost my entire way of life, and then found out that you were secretly trying to steal my love interest.
Lin:I sacrificed my position as the head of the Metalbending Police and even my metalbending and earthbending powers for my ex-boyfriend and the family I could have had because I was selfless enough to realize that the last airbending family needed to survive and I could help, even if it meant sacrificing myself.
