Ive Had This Thought Rattling Around In My Brain For A Thousand Years But I Wanted To Wait Until I Got

self rb because this is on my mind again <- my prev tags im honestly surprised its not a more common au “what if [character] had siblings” is a really common concept and with reid that changes his story significantly regardless of the age of the sibling i suppose maybe because like there ARE “reid has a sibling!” aus but like a lot of those they often exist to be reader inserts or to have an oc to ship with a canon character so “reid has a significantly younger sibling who he has custody of” isnt as common as i thought it would be because it doesnt fit either of those very well am i making any sense? i have seen some aus with this concept but im just surprised they arent more and they never do it the way it is in my head!! /lh criminal minds fic concept spencer reid
