Love, Eventually

Lin is lonely. She has been ever since Tenzin left her for Pema. Sokka's love child, who he never met, is also lonely. Aang, Sokka, and Suki all watch sadly from the spirit world. Then, Suki gets the idea to set them up with each other. Is this their chance to find love, or will their pasts just get in their way? M version is on Ao3. Based on a drabble in my Lin drabble collection.
