Episode 18: Marcoh's Notes (2003 series)

Back in Central, Ed and Al scour the library for the elusive records of Dr. Marcoh. But a "freak accident" burned the library to the ground. With little hope of discovering the secret behind the stone, Ed must think outside the Box. Meanwhile, Scar battles it out with Lust and Gluttony.

After they learn that the library was burned, they meet a librarian who was taken off her job. She later on says that she has a photographic memory. Thanks to this, Ed and Al travel to the main branch of the library and learn the terrifying last ingredient: A living human being.

Meanwhile, after Scar is injured thanks to Lust and Gluttony, he wakes up in a town of his own people. He sees a boy, who found him, and shows Scar to his grandfather. The grandfather says that there are many more of their people. As the episode ends, we see the boy admiring Scar's tattoo. Scar then says he got it from his brother as a gift
