I don't think Heather has long left in the competition. I thought she would be very good but she seems to freeze on the dance floor and often looks like she is waiting for Brian to do the next move so she knows what to do next.
I think its her nerves coupled with the fact that she just isn't a very good dancer in comparison with Austin, Tom and Rachel. She's a trier though and I love her fighting spirit. To be in the dance off three times and survive and then have to come back the next week confident is something I personally could not do.

It was the song itself, not the singers' rendition of it. Totally wrong rhythm. Sometime think it would be a good idea to lock everyone involved in the show in a room and play proper Cha-Cha music to them until they get it...
