Fma au where Hohenheim and Father kept in contact so the homunculi are treated as Ed and Al’s weird cousins who show up sometimes and make fun of humanity. Lust and Gluttony move in for a couple months after Trisha dies because Father is technically listed as their next of kin. Ed’s State Alchemist application involves creating a bas-relief version of an embarrassing story about Wrath he heard from Envy. They find out that Havok is dating Lust and respond with “That’s my cousin! Gross!” Greed kidnaps Al but they just end up swapping blackmail material on his siblings. Ed bit Envy when he was two and Envy still isn’t over it. Lust keeps trying to give Winry wardrobe and/or life advice. Someone asks how Ed got to be the youngest State Alchemist in history and he just says “nepotism” with a straight face.
Envy shows up more often when the boys are younger and runs around with the kids in horribly confusing games of tag and hide n seek
