The color of her pubes reveals that she bleaches her hair to fit in with the Aryans. Maybe she's a spy!
For the umpteenth time, black pubes on blond people are NORMAL. Pubes gain their coloring from eumelanin, which is the 'darker' melanin which controls the expression of black/brown tones. Meanwhile hair color is determined by combination of phaeomelanin, the 'light' melanin that controls the expression of red/yellow tones and eumelanin.
