Episode 6: No doubt that I’m human | Fullmetal Alchemist chapters 12 & 13

Ed continues to fight #48 in the abandoned lab, but he has a trick up is armor sleeve. He manages to win, but before Envy and Lust arrive and take care of things before #48 can divulge any information that might help Ed in the search for the stone.

#66 introduces himself as the famous Barry the Chopper—what you haven’t heard of him?—and instead of landing a blow on Al, gets into his head about how genuine his sense of self is. 

The abandoned lab exploding breaks up their fight, and luckily Ed makes it out alive, but badly injured. Afterwards, he gets a talking to from Ross and Brosch in the hospital, Al continues to question his reality, and Winry agrees to make a trip to fix Ed’s arm… again.
