For the briefest of moments his face was twisted with confusion at whatever "invitation" the other man was implying was out there for him, but the added weight on his back was a clear enough answer for that. Surprised by the sudden shift, he stumbled his way forward a couple of steps before he managed to catch his balance again with one hand against the wall and the other gripping Ainsley's knee to not throw their combined weight around too much.
"Would it kill you to give a bit more of a warning? Wait, a...song?" he grumbled, eyeing the landing they could have fallen to had the carelessness been a total success. He had been expecting something loud and far too peppy for the hour and lack of...well, a proper situation, but the surprisingly soft voice at his ear as he brought them down the rest of the stairs startled him enough to cause another lurch down a couple more steps.
The words were silly, to be sure, but there was something about it that just struck with Keir. He couldn't pinpoint it, but he found nothing particularly unpleasant about the whole thing; it was like everything had been altered to mold around it in the moment. His entire focus was on the gentle song in tickling breaths that sent an odd chill across his skin, and the rest of the trip was hardly noticed until they'd finally reached the bottom and it stopped.
Tilting his head a bit to look back at his new acquaintance, he found himself wondering sadly why the music had stopped and if, somehow, this unfocused and easily distracted man had really been the source of...whatever had just happened. "Drink...? Oh, yeah, drink," he mumbled as he finally continued on to carry Ainsley out to the bar. Hopping up onto a stool, he glanced back again as he motioned with his head for him to get down and get on his own seat lest the thing have to go crashing down beneath the combined weight of them both.
"Well, what is it we're starting with today, Handsome? More mead? A nice beer? Perhaps a richer wine?" he hinted, hoping he could clear out with more free stuff today if he was still so well-liked. Getting what he wanted would just be icing on the cake.
