Roger was exactly the opposite of boring. He chose some kind of goal and made a point to go beyond it. He wanted to be apart of the Quidditch team...and he made Captain eventually. He wanted to date the prettiest girl in the school (got told no by Cho) and ended up going to the Yule Ball with a half-Veela. He refused to play reserves for too long and eventually was able to try out for a starting position with the Tutshill Tornados.
The point was, he was pretty damn extraordinary and had no sense of modesty when it came to it.
"Traumatizing? Only if you can't handle how good we look in it. Or somehow become blind before you can get a chance to look at it," he said, leaning back in his seat with a laugh. "C'mon Johnson. Just admit you want to buy it because you're just as appreciate of a good body as any other person. I won't tease you for it."
