What does Lan Fan have to be upset about? She seemed to have a modest bust. Though I guess since she can't show it off like Winry and Riza with all that ninja garb might be the reason.
Yeah. Lan Fan is the one in the back. If you notice, Winry looks a little larger than normal and is holding her hands over her belly, which would imply she's pregers, which would also imply this is post-story. The one to the right is adult May Chang.
