I'm mostly interested in knowing how Ed and Al's alchemy was inhibited. What comes to Ling/Greed, I don't really see why he would have done what he did if Ling was in control. I suppose he might be hoping to learn more about Father, but the fact how easily he controlled his body suggests another mind is controlling him. He was also quite a straight-forward guy, not so much a crafty undercover one. Now that he's a homunculus, I think he would run straight back to his own country if he was in control.

A jolly good episode for sure. This new series can't anymore be even compared to the old one.
