Heartwarming / The Dawn of Yangchen

• While all Air Nomads refer to each other as "brother" and "sister," Yangchen makes no secret that Jetsun is her sister.
  Jetsun wasn't related to her by blood, or maybe she was in the manner of fourth or fifth cousins, but it definitely didn't matter. The girl who cut up fruit in a stupid way but at least gave you the symmetrical pieces was your sister. The girl who showed you no mercy on the airball court and laughed in your face as she kept you scoreless was your sister. Jetsun was either the person who would listen to Yangchen cry with utmost patience, or the one who’d upset her in the first place.
