Fullmetal Alchemist: Brotherhood - episode 42 - 30 Jan, 2010

Alphonse, after regaining consciousness, realizes he was dismantled by the group to carry him back to the tunnels. May figures how to decipher the notes written by Scar's brother by rearranging and overlapping the pages, which reveal the nationwide Amestris transmutation circle. After further investigation, they flip over the pages, finding another transmutation circle used for alkahestry. Meanwhile, Kimblee encounters Pride, who tells Kimblee to carve out the Briggs Fortress blood crest. Elsewhere, Falman gets into contact with Breda, and Sloth finishes digging the tunnels. Hohenheim arrives in Liore, where Rosé and the other citizens are rebuilding, and finds an underground passage under the church of Leto. As he stumbles upon Sloth's tunnels, he is attacked by Pride but manages to escape outside its boundary, and then tells Pride to let Father know he would be coming. Meanwhile, in order to carve out the blood crest, Kimblee conspires with the Drachman military forces to attack Briggs Fortress, and Zampano informs Envy of Marcoh's location. (Source: Wikipedia)
