Let's see, Roy wasn't suppose to be in central until later when he was transferred from the east, I don't think Ed knew Armstrong/Hughes before Reole, and the whole alchemic circle in central is kinda a fucking impossible feat to do when "Father" knows everything that's going on and can just activate the no-alchemy-zone easily
I hope that this first episode will never be fucking mentioned again for the rest of the series, because I will fucking rage if flashback of this shit pops up when they figured out the plan of the homunculus to use the entire ametris as ingredient for their new philosopher stone, since for one, it will really takes away hughes' significance as the first person who actually realizes what was going on before he was killed
