Most of my favourite pairings were endgame - Jate, PB&J, Despenny, Sun/Jin. The main ones which weren't, in the sense of them reuniting with others instead, were Sayid/Nadia and Shannon/Boone, and I guess there's also my favourite Sawyer ships of Cassidy or Ana Lucia but I didn't have high hopes for those. And then there's Darlotte, which is sort of semi-endgame - weren't shown reuniting/remembering but probably would have been together if they did.
