Tsubasa/FMA fic: Part 6

Making good progress with the next few parts, so I've actually got a chapter up early for a change. ^_^ And unless anything turns out to need any unusually major revisions, I'd say I finally have a solid idea of how many parts I'm aiming for too.

Title: Catalyst
Series: Tsubasa/Fullmetal Alchemist
Part: 6/11
Summary: It's nearly always safe to assume that whatever trouble the Tsubasa crew wind up in, there's going to be a feather involved somewhere in the middle of things. And it's probably even safer to assume that where the Elric brothers are involved, it's never going to be the Philosopher's Stone.
