I don't think he's buying into his own hype, I get why he picked Innocent instead of something that would work better in the context of the show. Now this is totally the Cooktard in me speaking, but I honestly believe he was more inspired by his song than all the rest were by theirs. He knew he blew the performance, so I don't get the smug comments either.
If he survives this round, he'll probably go back to game-playing mode and make a smart song choice next week.
