Roxas and Axel angst!
The idea was supposed to be similar to an anime screenshot or a movie, and as the sequence follows along it's supposed to be a short story. I'll explain how it's supposed to go since many seem to get confused by it.
Basically, the first panel features Roxas and Axel. Roxas is encountered by Axel and he doesn't really remember who Axel really is, but slowly his memories come back to him as he reflects back in the past when he was in the organization with Axel. The scene before him reminds him of the exact moment when he was with Axel in organization 13(featured in the 2nd panel). The 3rd panel symbolizes how Roxa's memories begin to fade away from that one moment he used to cherish with Axel, and that makes him distressed and emotional, which is the result for the very last panel.
Hope that clears things up!
