I thought best friends were supposed to be the ones who did that. Or the ones who would be the best at it.

[ And there it is, the reason why Mary had always quietly pointed out that she wasn't one of his best friends. Because she hadn't felt as though she was adequate enough-- that best friends were people who could solve all sorts of troubles, as though it wasn't actually anything that difficult to them. And because she wasn't like that, because Roxas already had people like that-- she hadn't been sure how much someone else could really help, in their place. ]

... But I think I know now... that you don't have to be someone's best friend, to support them. You just have to care and want to help them.

So maybe it's surprising for you, but I'll keep doing that... and sooner or later, I think you can rely on it.
