Kya and Lin have not been seen interacting at all in the series. However, this does not mean that they have not interacted before. Their parents were friends and Lin once dated Kya's brother Tenzin so they most likely interacted at one point. At one point, Kya was with the Air Nation at the Northern Air Temple when the Red Lotus attacked. Kya was greatly injured and imprisoned in a cave along with the airbenders. Lin eventually arrived with others to rescue them.
Kyalin is a very popular ship in the Legend of Korra fandom, despite the fact that it is considered to be a crack ship. Many find the two to be a good match with Lin's serious and dutiful personality along with Kya's relaxed and hippie personality. A lot of fans stereotyped Kya as someone who would be attracted to women and many also believe that Lin may be attracted to women as well. Lin is known to have been single since her break-up with Tenzin and Kya also seems to be single, so many like to pair them together.
- Kya is known to be a part of the LGBT+ community, but it is unknown what she identifies as or if Lin is also a part of the LGBT+ community.
