While Al defends himself against the transmuted Barry the Chopper, Ed discovers more about the dark alchemic experiments deep within Lab Five. But the biggest threat of all may be Ed’s own morality, as he’s tempted with the ultimate power he’s been seeking for years. Hughes issues an order to allow Armstrong, Bloch, and Ross to investigate what’s going on inside the 5th laboratory. Now Ed sees that Tucker was hiding the fact that there were human prisoners involved in the making of the stone…and that Ed would have unknowingly killed them. But Lust has Al held hostage… forcing Ed to attempt the unthinkable. Meanwhile, Al’s recurring questions about his existence come to a boil. Was there ever an Alphonse Elric? Or are his memories and soul alchemically created lies?
