Well at least he protected him and made him immortal unlike his women lovers haha.Ganymede was one of the reasons that Hera took the side of the Greeks in the Trojan War. Not only was she annoyed that Zeus had another lover, but he had even supplanted her daughter, Hebe, as cup-bearer to the gods, and Hera felt it was disgraceful that the nectar of the gods was being tainted with human hands. Ganymede had been made immortal by Zeus, so Hera could neither hurt him nor express her rage on Mount Olympus, but she often refused to accept the cup when Ganymede was serving the gods.
