Ep 12. One is All, All is One

In Fullmetal Alchemist: Brotherhood season 1 episode 12, titled "One is All, All is One," we see Ed and Al continue on their journey to find the Philosopher's Stone in order to use it to restore their bodies. Their travels take them to Liore, a city known for its false prophet, a man named Father Cornello who claims to be able to perform miracles through the power of a stone called the Red Stone. This stone is later revealed to be a fake, but not before causing some chaos in the city.

As Ed and Al make their way through Liore, they discover that the town is being oppressed by a group called the Black Bats, who work for Father Cornello. The brothers decide to investigate further and end up stumbling upon another secret within the town: a girl named Rose who claims to have been saved by Father Cornello and now serves him as a devout follower.

Ed and Al soon realize that the real source of Father Cornello's power is not the Red Stone, but a Philosopher's Stone. They confront Cornello, who transforms into a grotesque monster, revealing that he had used the Philosopher's Stone to gain power and influence in the town. Ed and Al engage in a difficult battle with Cornello, utilizing their alchemy skills and quick thinking to try to defeat him.

One of the key themes of this episode is the concept of equivalent exchange, a core principle of alchemy. In order to create something, alchemists must give up something of equal value. This principle is demonstrated in various ways throughout the episode, such as when Ed creates a spear out of the materials around him in order to fight Cornello.

Another theme that is explored is the idea of faith and what it means to truly believe in something. Rose's unwavering devotion to Father Cornello is contrasted with the brothers' skepticism and questioning nature. Through their experiences in Liore, Ed and Al start to understand the importance of having a purpose and a sense of direction in life.

Overall, Fullmetal Alchemist: Brotherhood season 1 episode 12 is an exciting and action-packed installment that further develops the main characters and explores some of the show's key themes.
