Susan tutted to herself as Justin blushed redder than a Gryffindor flag. Justin had always had a definite thing for Wayne during school, and now of course he had a definite thing for Seamus. Normally this would have been fine - apart from the fact that Seamus was in love with Dean - except that Wayne was back in town, and Susan knew it was only a matter of time until that came boiling to a head. Which could probably be followed by Dean and Ophelia breaking up and Seamus and Justin following suit. Really, all they needed was Wayne accidentally getting Ophelia pregnant to create an ironclad little pentagon of romantic woe* for the five of them.
Susan lifted her eyebrows at him and gave him a look. "We all enjoy some 'alone time' every now and then," she replied with finger quotes, sipping her wine and watching him plate up their meals. "What, the quiet puts you off your masturbation," she teased, following him over to the table. She sat down and pulled the plate to her, surreptitiously tasting it before eating it - a combination of Auror training and knowledge of Justin's cooking skills informing her decision to do so. Luckily, she found it perfectly acceptable and began to eat properly. "So you go to Finnigans? I suppose that makes sense, given that you like getting screwed by the publican?"
OOC I may have actually had to draw myself a diagram to work this out. Enjoy:
