There is a rumor that Jessica will be dancing a jazz number tonight which is in her field of excellence - if so, that should help neutralize any damage done by the Benji swing number last week that did not go over well with the judges, got Nick eliminated, and didn't do Jessica any favors either.
I am still half of a mind to think that knowing that Nick was in the bottom 3 votes, Nigel purposely placed him with Benji and his tough swing choreography. I think, though, that Nigel hoped that the talented Jessica could possibly pull that one off. That is why I think Nigel tore into the two of them and the choreography.
If Jessica does get a jazzy type number where she can show off, I think it may be Nigel's way of making it up to her even though she may, alas, be in the bottom 3 at the start of tonight.
