Cly was best friends and traveling buddies (occasionally lovers) with Hades and Hyth. They were a mentor and dear friend of Themis (and later Erichthonios). They barely got along with Lahabrea (mostly out of professionalism) and HATED Athena once they finally met.

Last but not least is their dearest love, Hermes. Cly didn't meet him until after the Elpis incident, but thought their meeting was ordained by fate. In Hermes Cly found a kindred spirit, as they struggled with grief and anger of their own.
