Mako discovered he was a firebender at age four.
He remembers the night clearly. It was a warm spring night. Their family lived in a crowded and rundown apartment complex; the place had three rooms, two bedrooms and a kitchen/living room area on the second story. Their parents had sent both him and little Bolin to bed early. With no voices or movement coming from the street or other apartments it was an unusually quiet night. Almost as if no one dared to make a sound. The silence and Bolin nudging his side and drooling on the covers kept Mako awake.
It all happened so quickly that he's not sure what came first: the smoke or the screams.
