Nick really screwed up his HOH by not listening to Nicole. It reminds me of last year when Kaitlyn was misted so hard by Tyler that she put up Swaggy. Its painfully obvious that Nick and Bella wanted to be in with the cool kids so bad that it cost them their game.
I think a season with a few more older players (or more people who are generally confident) would result in less situations like this and ACTUAL strategic game play.
