edward using his coat as a blanket because he let al have the real blanket can be so personal

I'm gonna say that if the average interaction between Ed and Al can't be distinguished between them brothering brotherly and incesting incestuously by the average FMA fan, then yeah. There's obviously some... brothering incestuously. Incesting brotherly. Going on.

exactly. exactly this.

[this may all be speculation] alphonse elric likely bases his identity around his brother. he’s a relationship-oriented person. without someone to guide/support/love him, without closeness to an individual, he’s lost and confused. when his mother died, he clung solely to ed. he always defined himself as ed’s younger brother, and how he sees himself revolves around how he sees ed (mangahood supports this with al commenting on himself, and all those comments being in comparison to his brother–he’s the nicer brother. he’s the more patient brother. he’s the more mature brother. his brother needs him to balance him out.) also, a large part of al’s ego is that ed needs him. but in return, that means al needs ed to fuel that ego. just like ed has an ego that says “its my job to protect my younger brother,” al has an ego that says “it’s my job to take care of my older brother.” their relationship is extremely codependent because of these psychological needs. combine this with al’s identity for himself all revolving around his relationship with ed, and you have a subconscious reason for al’s obsessiveness in getting his brother back in cos. notice how he dressed exactly like ed. he has no personal identity for himself beyond his relationship with ed, and ed is gone, meaning he assumes his brother’s identity. 

i don’t think al has like internalized homophobia or anything he’d just be genuinely confused at the idea that he’s not actually interested in girls. but girls are so cute and fun and little of course i like girls… i mean yeah ive never imagined having a girlfriend or getting married and i dont want to kiss or have sex with girls and i do want to spend the rest of my life with brother and it makes me feel funny when his skin touches mine but that’s just how everyone feels about their big brother obviously

i do like drawing parallels between winry's comphet and ed's incestuous desire because i want to make the audience uncomfortable all the time
