All the darker pics they're using to show which players are eliminated are uploaded and are ready to be switched out, except Nick's, which implies he's left at the end. Since he's done basically nothing suspicious - in 14 challenges, the only things he's done that have cost the group money are taking those sleeping mats and his two slips with the gutter - he's infinitely more likely to be the winner than the Mole. And we already know he suspects Shaun, since he gave Shaun his freebies to get them out of the game and save him from being eliminated. Which... isn't too surprising, since Shaun has basically tried to sabotage every challenge in every possible way.
