It was a little sad to see JJ eliminated, since she was an early favourite of mine, but realistically it was her time to go. Still not sure how Derek is still in this, as aside from a few dramatic moves in the group dances he does really fade into the background.
Am curious if, as a dancer, it's easier to be eliminated after an injury (like JJ), or after a great performance (like Edson). Is it frustrating to get booted after one just nailed it, or is it preferable to have one last chance to show off one's skill? At any rate, at least they both get to go on tour, so that's some consolation.
