It's weird how Peridot's female characteristics became less pronounced. Logically it should be reversed since her concept of what being "female" is would be greatly change after being introduced to earth culture. Like what female means means something very different to a group of asexual mono-gendered aliens verse a race who uses traits associated with their gender as both a way to attract mates as well as a direct way to express themselves and compete against others even outside of mate attraction.
