"Then maybe," Remus conceded, his gaze pulled to the water. It looked like a post card, and if it wasn't for his arm, Remus might have been tempted to jump in already. There was, of course, the matter of Sirius's intentions if he did want to swim; would he go in fully clothed? The question definitely had some merit, particularly if Sirius's judgement were impaired...
It was wrong to want to take advantage. Shamed, Remus accepted the bottle. It tasted strong, and bitter yet sweet. But it didn't do anything to dispel the images the idea of Sirius swimming in that pool conjured. He passed the bottle back to Sirius before leaning back on his good arm. "This is a very, very nice spot you've found. Well done!"
