Fullmetal Alchemist Volume 20: 01/23/12
Fullmetal Alchemist Volume 20 by Hiromu Arakawa builds on the alliances begun in the previous one. Ed with help from the chimeras focuses on his recovery. Meanwhile Al, Mei and Scar come up with plans to fight back based on what they now know.
The lone wolf, though, is Greed in Lin's body. There's an internal fight between two very strong personalities in one body. Normally I dislike the shared body plot but Greed and Lin are both interesting enough to make the plot work. Most interestingly, Lin is able to warn Ed about the "Day of Reckoning".
Al's group heads to Leor. He hooks up with Rose as well as another familiar face. Here's another point in the story where the manga (and thus Brotherhood) is a significant departure from the tangent taken by the first anime series. Rose in that version ended up a very broken character. Here, though, she's a strong, confident and happy leader. She has risen to the occasion and has helped keep Leor together after all the riots and military run mayhem.
