The eyes have it

Rebekah has very pretty blue eyes. Strangers are always commenting on her hair or her eyes. But what nobody notices is that one of her eyes is not entirely blue. Her right eye has a brown spot. It started as just a spot, like the head of a pin. It is slowly expanding. It is now across the whole top of her eye. It will be interesting if she ends up with David_Bowie_eyes (well, his aren't really different colors).
