He was about to give her something of a lecture on turning down very nice Russian vodka when she took to chewing on her lip. It wasn't a particularly good sign when she took to worrying at her lip like that. Now that he really took a proper look at her she seemed rather out of sorts in a strange sort of way that James couldn't place. Maybe she was a bit worse off than she let on; some healing spells did a number on one's stomach. James wasn't completely ridiculous, despite her occasional accusations, and he could concede a few causes to pass up such a treat. After drinking down his own, he set the empty glass down on the counter just behind her.
Only for the briefest moments did James falter. Sure, he quite nearly dropped the second shot glass - because seriously, no set up, just straight into a sentence that packed the same blinding force as the lightning storms that rolled off the Bermuda Triangle? Merlin, for a minute there she almost had him. Instantly drawing up his grin, he let his unoccupied hand settle along her waist. He managed to avoid snorting a laugh through his nose. Pregnant? It was totally absurd.
"Yeah?" James replied with a bit of a laugh. It was a lousy sort of joke, and smacked of the sort of thing Sirius might've put her up to. Fair enough, then. He wasn't about to rise too much to that sort of bait, but he knew the game well enough to play to the set-up. Still grinning he asked, "So just who is it you've been sneaking around with, then?"
They couldn't have thought this too far through. James' child-siring days were over, something he'd reached a vague sort of peace with. For the joke to work it'd have to rely on the premise of her fooling around with someone else. However, try as he might James couldn't see the punchline, which had him starting to think that Remus was in on it as well. Well, maybe not. Then again, when Remus was younger, Merlin he'd had such a quick, sharp mouth. It seemed to have tempered over the years, but with enough prolonged exposure to Sirius.... well, no measure of maturity, even in Remus (especially in Remus) could stand much chance against Marauder influence.
