"They're rather lovely eyes," Roger pointed out, because while he wasn't one for staring soulfully into someone's eyes, he was rather fond of getting close enough to a bird so that he may sneak her a quick kiss. So if he had to indulge a little romantic cliché to get closer? He would.
He shifted around, so that he had angled himself even closer to her. Leaning forward, he brushed the shell of her ear as he whispered, "But I honestly think your smile is your best feature." Yes, Roger knew how to lay on the charm thickly and exactly how much he would be appreciated in someone else's personal space.
In this situation, he thought that the answer was 'Very much so, please and thank you!' He may have not been a Veela - or even half-Veela as Fleur was, but he had perfected his technique down to an art form.
