Half of their hcs and fanfics sound something like this
"Okay so! Regulus betrays Voldemort because his love for James shines through,,, hes heartbroken that James eventually chose Lily instead of him and opts to die trying to help him instead of devote himself to Voldey (Kreacher?? whos that???)"
Literally stole their whole damn story? the whole dynamic is snily? and then at the same time they probably portray Sev as some misogynistic asshole like bro your favorite character is a Sev rip off.
