Aww. :) I loved how worried Ed still is for Al, even though he's back safe and sound. I hadn't really thought about the fact that Ed hadn't kept his promise to Winry about coming back with both his missing limbs, so I liked you bringing that up.

The story feels a little rough, though. As the previous commenter noted, you've got part of a missing sentence or something in the second paragraph. Also, your second to last sentence seems to be missing a couple of words or something. It sounds like you wrote this pretty quickly, though, and you did a pretty good job for the time you had. :)

Something weird happened in the second paragraph...

"It was, quite possibly, the most absurd thing Alphonse could have 'd been walking home for the past hour, stopping and letting Alphonse rest as he needed to."

It seems like part of the sentence(s) disappeared.

I thought it was nice and in-character.
