I'm not sure his stunt leaving with me like that really helped things with Winry but. I guess I can't say I would really expect anything else from him, when it was supposed to be all hush.

[It wouldn't be good if everyone found out that Ross was out there, heading to Xing and all. That she was alive when officially, she was reported dead and all. But through everything, even if this was a different Alphonse, he was still very much Al. That Ed can't help having that familiarity all the same. In the casual teasing or the casual way he talks about things together. He follows without a second thought, figuring to head up and go with Al to try figure what was going on and how they could fix things.]

Unless what? Maybe I can help. Ah, that is, alkahestry is like a sort of medical alchemy? From what little I've gathered. It's from Xing.
