Rachel Berry is the Jewis icon of William McKinley High's Glee club. She's known for having a very remarkable nose, a powerful voice, and wearing knee-high socks, pretty short skirts and argyle cardigans. And bossy personality, too.
Also, she's secretly in love with Quinn Fabray. It's just that nobody realises that.
