Gawain had a surge of hope, but that was dashed when he noted the tone of her voice, even before she got to the 'but'. He hoped he didn't look as embarrassed as he felt, though he covered by taking a long sip of ale. Apparently he still tended to like those witches who weren't available. It figured.
"Ah, well, congratulations then," he said, recovering and nodded. "You didn't give me the wrong impression, I think I was just a bit hopeful." Well, she had, somewhat, but a gentleman wouldn't point that out, and Gawain prided himself on being a gentleman. Mostly. A gentleman wouldn't find someone else's girlfriend or wife attractive, most likely, but no one was perfect.
He cleared his throat, hoping to smooth over that awkward patch.
