Ruby and Velvet are my favorite so I’m down for that
this is essentially an AU where we can do whatever we want so... what if Ruby and Velvet wake up as sisters, their 16 and 18 but in this universe anyone under 21 is treated as a baby, and then Weiss and Coco are their mothers with Blake Yang Nora Ren Pyrrha and Jaune as aunts uncles and babysitters?
