Now the time is here
For Iron Man to spread fear
Vengeance from the grave,
Kills the people he once saved
Youswell was a perfect place to start unleashing retribution. Isolated, hardly any visitors, no families living half in one city-half in another. Word of what happened wouldn't get out fast and more to the point; no one would see him.
At first, he thought about taking their souls from their bodies and trapping them in various objects but he didn't think he could do that. Then he thought he would kill one and use two or three others as ingredients in a human transmutation: 1) it was too dangerous for him, 2) he'd have to do it over and over – too tiresome, 3) he might as well just kill them all. So 3 he went with; kill them all—using alchemy of course. All through the day he snuck around picking them off one by one like flies. To make things go quicker he drew transmutation circles on his hands. It was chalk so it would come off easily however the blood was another matter: it could be washed off but the smell would remain. "Hm, I guess there's more than one reason I walked all the way out here. I could run back to the nearest town when I'm done, buy a train ticket to Youswell, call Ed or Mustang to tell them where I'm headed, take the train there, then when I see the city in ruin with all its inhabitants dead, call Ed or Mustang again to tell them about the town and that I'm going to help bury the dead. That will give me a perfect alibi for where I've been, and the stench on the armor. And if they wonder why I showed up in town coming from Youswell on foot, heh, no one could ever suspect innocent Alphonse of doing such a horrid thing."
Another one of the people came out of the coal mine. It was a young girl who had taken lunch to her father. Didn't matter. Al jumped out in front of her. She was startled, turned to run. Alphonse grabbed her head with both hands. Red light from alchemy came forth and exploded her skull. Al dropped the lifeless body heading for the coal mine itself. "I really should thank Scar-san the next time I see him" Alphonse said then chuckled aloud to himself.
