Percy gave a small shrug and a smile, "Yes, he would not want this much focus on himself. He never did seem one for much attention," he said, as he ate a bit himself, "So, why not a bit of socializing before we talk shop? I believe it has been a number of years since we both roamed the halls of Hogwarts together. How are things with you?"
Percy thought it was a safe way to sort of guide the conversation towards friends. And then, after they sort of set a more casual tone, he'd look at the sketches that Dean had brought and give him a chance to create some ideas.
