This wasn’t supposed to happen.
#that line more than any other defines their relationship i think #their relationship wasn’t //supposed// to happen #castiel wasn’t //supposed// to stay #but dean and cas fucked the system #broke the rules #defied fate //together// #and kept clawing their way back to each other no matter what obstacles stood between them #there is literally ALWAYS something impeding them from getting back to each other #fights and torture and mistakes and circumstance and dimensions themselves #the foundation of their relationship is conflict itself #a faithless man rescued by an angel sworn to heaven #yet dean through cas gained faith. cas through dean gained free will. #despite everything keeping them apart dean would still rather have cas cursed or not #cas would still choose dean over all because dean is kind of his world if we’re being honest #they were never //supposed// to be allies #to be best friends#to be maybe more #but they were #they //are// #because they make it up as they go
