Don't they have all the judges from that season sitting in at the very last show? I seem to remember the panel being crowded in previous seasons for the last show (can't remember if it's performance or results though). I think this spoiler is a bit confused or unclear when it comes to the judges.
I don't see Brandon as being thrown under the bus. He's done HH and has shown that he is very good at it. If anything I see Evan as getting the short end of the stick since I doubt he will be any good at HH or at Jive and the two Jazz routines could be disasters if they don't play up to his "quirkiness".
I actually think for the most part the routines are fair and have the potential to be either disasters or successes depending upon the choreographer and what they do.
The one thing I find odd and a bit telling is that the girls have very similar routines that are right in-line with what they do. If you are buying into the whole manipulation thing then comparing what the girls got with what the guys got it would seem that they want a girl to win since they were both given routines that they could shine in.
I just realized that Evan was given a HH to dance with Brandon. So maybe he is being thrown under a bus... a very small VW bus though since if the HH is that slow flowly story telling stuff this show like so much he may be able to pull it off.
