Episode 19: The Truth Behind Truths (2003 series)

Four years, Ed and Al have devoted themselves to searching for the all-powerful Philosopher's Stone. But they have learned the Stone's secret ingredient: Human beings. How can then reconcile their strong desires to fix their own bodies with the knowledge of its gruesome costs? What could possibly justify the mass extermination of human life?

In the beginning of this episode, we hear Al talking about the Philosopher's Stone. Then,taking place after the last episode, we see Ed, Al, and 2nd Lieutenant Maria Ross still in frozen shock after hearing the last ingredient. Ed, repeats that the last ingredient is live human beings. Cuts to the theme song.

After the theme song, we see Maria Ross chasing after Major Armstrong and saying that they {Ed and Al} have had a long day and tries to convince him to let them relax. Meanwhile, we see Ed and Al staring dully at nothing. Ed says that they will have to be that way their whole life, as he can't bear the thought of having to use living humans in order to create the Philosopher's Stone.

Later on that day,we see Al trying to convince Ed that perhaps they misread something. In a rage, Ed says, "He's had enough," and hits a teacup, which accidently lands on Al's face
