I've decided her name is Cerulean Pearl Schnee . She went by the last name Spierwit when she first ran away after her mother died. She was a first year at Beacon when Winter was a first year at Atlas. At the timeline of our RP she will have her normal white hair uncovered and go by the name as a Schnee. She wears slim slip-on diapers when she sleeps as she has wet the bed her whole life. Winter does not know this. No one outsided her Team and immediate family knows.
