Which sentence supports the inference that Jim loves Della for more than just her looks?

Jim drew a package from his overcoat pocket and threw it upon the table.
“Don’t make any mistake, Dell,” he said, “about me.”
“I don’t think there’s anything in the way of a haircut or a shave or a shampoo that could make me like my girl any less.”
“But if you’ll unwrap that package you may see why you had me going a while at first.”
