"When talking, Marvin often looks away to the right. Some might say that this means he’s deceitful, but that is not the case here.

"Looking to the right is associated with positive thoughts, and what we see is the former boy-bander trying to cheer himself up with positive thoughts, because he’s a little nervous about the weeks ahead. He’s determined to do well and has already decided that he’s winning the entire thing."
