Pretty sure that's besides the point. She's saying that he was clearly influenced by him since he came into the competition more plainly, and started dressing like Willy as it progressed.
Or maybe it's because the first pictures are from the casting itself, where people don't usually dress up
If he was 'really copying' him, why wasn't Willy more flattered? Willy is a nobody. He should have taken it as a compliment that even because he's a nobody someone wanted to 'copy' him.
