Zavala and Caitl are implied to be starting Zavala had a wife Amanda and Crow were thing until she learned the truth. But is sounds like now she’s conflicted and coming back around. Cayde had a family, including son, prior to becoming an exo. Though some have suggested that was fabricated. Cayde had a crush on someone as an exo while he was stills working for Bray. I believe it was one of the Bray sisters. I don’t recall if it went anywhere. Does it matter? Any of the relationships in this game get very little mention outside of the lore. Most of our NPCs are immortal superhuman soldiers that are a mix of humans, mutated/evolved humans as Awoken, and robots that are only slightly more human looking than C-3PO. In their centuries of living, what does it matter to you if the robot they loved had dangly bits.
