On Grey's Anatomy tonight, I recognize the teenage girl that played "Marissa".?

I know I have seen her in something when she was a little girl, a movie I am thinking. I missed the end credits, so I have no idea what her name is. Help! She was the girl with the long dark hair, that wasn't popular, whos best friend Danny had the pencil stuck in his eye and wound up in a coma. I know it is dumb, but it is gonna drive me NUTS!
