I like to imagine a renegade interrupt that is simply slamming your fists into the table, glaring at jeff, him getting mildly nervous but somewhat aroused from the intensity of shepard's stare, and then kissing him fiercely, grabbing onto his shirt and knocking his cap off, and then, finally, jeff would simply give in, forget all the barriers he had built up to deny there's something between him and shepard, and then, he'd just kiss her back, slowly, thoroughly, lovingly
Honestly though, I just like to humbly imagine that this convo never even took place. lol. i like to imagine that these two nerds are already happily together and that Joker is asking a very hesitant Shepard to dance, He eventually goes to the dance floor (with the other crew members also joining in and having a good time) while he does his little cute wiggle dance. He then proceeds to reel her in by the doing the actual legendary fish reeling dance move. He doesn’t stop, and eventually Shepard rolls her eyes but gives in and shimmies towards her beloved pilot while the others whoop and holler XD
