>>31018811They are the true "alien" of this game. They and their "sidequest" are the leftover from XY game that was forced into Alola. In the close-bit community of Alola that everyone seem to knew each other (like how Mina is acquainted with Ilima, despite being on the opposite islands. Or how the Kahuna who gave you your first pokemon was also the ex-mentor of a local evil team's leader.) No NPC ever mentioned Dexio and Sina at all and Zygarde has no place in Tapu-UB-cosmog family lore. If you cut those two and their sidequest out from Alola there is no consequence at all, while if you cut off,said, Molynne, you cut off Sophocles's cousin and Kukui's old friend, who may had history with Hala and Guzma as well.
