Hm, Scott did not care for Logan's charming smile. He knew it did nothing for Les, but there was just something about when a single man flirted with an engaged woman in front of her fiance that showed him how little respect that man had for either person. In this case, no respect for Les or him, at least that's how he viewed it.
It was Logan's own fault he wasn't the man standing beside her. But he wouldn't change a damn thing about that and was pretty happy it was himself. She made him happy, happier than he had ever been and he wouldn't trade that for the world or the best photography job a photographer could get. She was special and he knew that.
