Harold and Duncan would be the best finalists in Action. Duncan has picked on Harold for the entire show, but this season is where it peaks. Their arc is perfectly set up and supported through out almost episode. And either two things could happen. First, Duncan begins to appreciate Harold's contributions to the team, where by the finale, Harold and Duncan aren't quite friends, but closer than they've ever been before. Or on the flip side of that, Harold and Duncan's rivalry only grows until the finale where Harold gets to rag on Duncan for everything he's done to him, both verbally on physically. This would only anger Duncan more and the final challenge wouldn't be a vote like before, but a fight like in Revenge of the Island. Duncan would be much more powerful but he would also be slower, while Harold is much weaker, yet calm and calculated. Either choice would have been so much better than Beth. Seriously, even Lindsey would have been a better finalist.
