I still don't understand Ray's psychology. Even if the memory is changed, why is he supporting Jim in his genocidal conquest, which cost thousands of human life. Also he is an experienced god slayer surely he knows this war will bring attention of the celestials to earth or humanity. He once sacrificed himself for humanity(i maybe wrong about this part, its been so long i dont remember correctly), that's why he lost his body. Ray just doesn't act in character, according to me at least.
Well I still think Ray's memory is intact, or at least knows Quinn is not what Jim claims he is but just wants to fight Quinn with everything for his excitement, there's also the probability that he's preparing to go against the ancient ones and wants to see Quinn's capabilities to go against the ancient ones together. I as well think the planet they're about to fight on will totally be destroyed maybe like Asura's. Only one move from either Ray or Quinn may take out Dober's monitoring device.
