D has had to go through this transformation in his psyche to connect with Y. There's no other way. It's not that D needs to catch up to Y. Rather, he needs to surpass him so Y can fully rely on him. Remember Y has had a very traumatic past and the walls around his heart are iron clad and his respect for himself are non existent. He also doesn't really have much respect for anything or anyone. D will probably have to dominate him initially a bit so he comes around. To earn Ys respect and let him open his heart. Don't worry folks, By the time they get together we are all going to be old and wrinkly. Not that there's anything won't with that. Patience is virtue.
