Sloth isn't 'caged away.' They said that they have to keep him working. He's off doing some important task. I've watched a few people recently reacting to this show and it surprises me that so many people refer to the homunculi as "The Sins" when they're never named that in the show. They usually get referred to as homunculus/homunculi in-universe, so it's just interesting to see that folks for some reason gravitate to calling them "The Sins" like some kind of title. Interested to see more thoughts. Hope you stick with the show.
I remember them saying that he's working, I must've just got mixed up in the moment when recording. And yeah I just resorted to calling them that due to them literally being named after the seven deadly sins 😂 I just wasn't sure if they were the ONLY homunculi in the show. But good to know, I'll try to refer to them as that going forward! Slip ups may still occur though lol
You can refer to them as the homunculi. Also, prepare yourself for cliffhangers galore in this series, and once the show picks up, it does not slow down. A lot of reaction channels watch in 2 episodes, so they don't go crazy waiting lol. Also, there are some after credit scenes for certain episodes, be sure to look up the list of them. Or just check after the ending songs to see if there's a scene. I'd recommend NOT watching the "next time on FMA" parts, there could be spoilers in those.
I will definitely look up a list of the after credit episodes and see what I missed so far. This is the first I'm hearing of this 😂 I certainly would like to watch two episodes back to back at some point. We'll see!
Also while I'm here, there is a double meaning behind the scene with Roy at the grave of Hughes. He mentions it's going to rain, and cries, but the other meaning, is that he's "useless" on rainy days because he can't perform his alchemy then. No matter how powerful he is, in that moment, he's helpless.
I know I'm late to the party here, but you asked something like "alchemists create guns, but it doesn't seem they gave anything in return" This misunderstands the fundamentals of alchemy. Basque Grande (the Iron Blood Alchemist) didn't just "create" guns. He transmuted surrounding material in the environment, deconstructed it, and then reconstructed it into weapons. Equivalent exchange isn't really "giving up" something to "create" something else. You take something that exists, deconstruct it, and reconstruct those materials differently.
