I'm still at how Nia didn't make it onto this past challenge. She WAS the show so for Jess (out of all of the cast members) to be on in place of her is crazy but hopefully she'll be on this upcoming season.
That Avery girl didn't want to do the show, according to Nia, so since she didn't want to do the show, the producers went with someone else.
They better not be trying another exes format, though... I want another Duel, or something more like Cutthtroat. However, I do see a lot of former couples there so...
