Reason #2 Legend of Korra will make me cry: Mako and Bolin's past.
I know Mako is the kinda person who looks out for his brother no matter what and its sad that their life has not even been half-decent for a very long time. Every time I see a clip of Mako getting hurt, a single tear runs down my cheek. Either that, or I scream, "HE ELECTROCUTED MAKO???!!!"
Anyway, the story of this pic is that Bolin lost his gloves and Mako then practices his firebending continuously so he can keep the energy in control while he warms Bolin's hands at night.
Also, Bolin gets all the big, warm clothes because Mako is a damn good older brother.
