"You're beautiful. I've seen you so many times, and each time I look, you become more beautiful. I'm lucky to have you as a soulmate. I'm sorry I can't tell you who I am. You'd never guess and I may never say. But I want you to know that I really do want you."

If he doesn't, he may never find out because his soulmate will be GONE and he'll have to live alone in a world without color. Will Castiel be able to figure out his soulmate's clues? We all know who Castiel's soulmate is, but if he finds out too, how would it happen? What would life be like if he never found out? Or better yet, should he WANT to find out in the first place?
