Days I really loved how they explored the formation through identity and watching Roxas slowly puzzle this big new world together. It's especially adorable when he comes to the wrong conclusions about things and then you sort of watch him try to meander through why the world isn't lining up with perception. And I think Days has his most powerful line which is "heh..Where did I think I could go". It's sad impossible sad and powerful. All game you want Roxas to break away from the Organization and strike out on his own, and when he does it really hits home how he literally has no where. The bad guys want his life, the heroes want his life, his friends have all left him, and he has no goal nor any place to start. All he could do is head to the clock tower, it's the only place he ever felt was home, and even then it just reminds him of everything he lost. He literally has only Xion left, that's his only hope, and as soon as she appears you know what is coming...and it's just so raw and heart breaking to know you're at the final moments where Roxas loses the last bit of everything that matters to him. Not just Xion herself but his life with her, the memories themselves will be robbed from him.
