She was definitely a nervous dancer. You could sort of tell some nights her body language was just off and she'd give a rather tense, frozen performances with a bobble here and there to give the impression she wasn't sure. She could also be incandescent.
Like her Aurora -- I saw her fall off pointe in the very first balance and struggle through an entire Sleeping Beauty, and also saw an Aurora so harmonic and musical that it was like she was born to dance the role.
She always seemed to dance better with Cornejo -- she was short enough for him to partner, and their relationship onstage was so beautiful that I'm sad to read that behind the scenes their relationship was not good. I guess that's why it's called acting.
