The train station thrums with digital announcements and the shuffle of crowds, but Aang is a vortex of ancient stillness and modern energy amidst the steel. He perches on the edge of a trash can, arrow tattoos glowing with a soft, anticipatory light, ignoring the sideways glances of commuters. When the train hisses to a halt, steam billowing, he spots her instantly. A cry of pure joy escapes him, and the Avatar abandons all dignity, launching himself across the platform to collide with his sister in a hug that defies both physics and the weight of time apart, his heart hammering louder than the departing engines.
