I think there is something else with Casey. When they saved him they had to bleep out several things he said, he didn't seem to have the ability to supress it, he looked like he was going to vomit too. Also at the end of the show he had a doctor attend to him and even go out on stage with him, they showed that on the next episode. There have been other subtle hints that something is going on with him, it has been mentioned more than once that "you can do this." His eyes seem to be wild to me. I'm not ragging on him, I'm just saying there is something about him that has my antenna up.
I would have been OK with Pia being in the top three. I realize she didn't connect with the audience, or at least that's what a lot of people said, but that can be worked on. Look at the guy who kept closing his eyes (I forgot whcih one that was), talk about no connection. Pia still had the best voice and would have been very marketable.
