Scar luckily arrives and helps a disadvantaged Al defeat Barry. This causes Barry to set off explosives, freeing an imprisoned Greed as well as others around him. The older Slicer agrees to take Ed to the interior of the laboratory, but the younger Slicer breaks his blood seal after Ed calls him human. Solf J. Kimblee, the "Crimson Alchemist", and several other prisoners are led by a fake Grand to be ingredients for the philosopher's stone. Ed and Slicer are attacked by mutant chimeras until they are called off by Tucker, who, after his death was fabricated, has become a chimera himself. As Al and Scar travel into the laboratory, Scar reminisces about his brother and Ishbal, but they are attacked by Lust and Gluttony, who Scar reveals to be homunculi. Tucker shows Ed around the laboratory, who realizes that he has been given the opportunity to create the philosopher's stone.
