I've missed a few episodes, but it seems like they haven't done as much runway this season, but a lot more "challenges". IE, evade the paparazzi, to me that's not as important as being able to walk a catwalk. But i'll vote for Nik. For some reason Nicole irks me. I think it's her annoyingly redundant "okay" in panel each week, each week, each week.
See how annoying that was!
