Dorcas wasn't very good at being serious. She could be when the situation called for it, but her tendency was to joke her way around things, especially the more difficult things. That sometimes got her into trouble professionally - at the Ministry and with some of the higher ups at SHIELD - but it was also a part of why she made friends so easily. She had that sort of humor that seemed to put people at ease.
"Why, thank you, Mr. Wood," she answered his compliments, rewarding him with another smirk. Dorcas was a confident girl, but she didn't hate hearing him say she was fit for any age. "You're not so bad, yourself," she added. It was a bit of an understatement, but she wasn't going to just come out and admit she thought he was quite fit for any age, too.
She laughed again when he asked her age. "53, of course. I've done the math." She chucked at her own joke and then added, "I was 21 when the big blue box grabbed me, so I guess I'm legal even by America's standards. Not that it would have stopped her, but she was rather glad she was old enough to buy her own alcohol. "But you can still corrupt me if you like," she added, a mischievous grin spread over her lips.
Her expression grew a little more serious when he told her - or hinted, rather - about what had happened to his friend. "I'm so sorry," she told him, instinctively placing a comforting hand on his arm for just a moment as he flopped onto her sofa. "I know how- losing people is never easy." A part of her wanted to ask how it had happened, but she squashed that natural curiosity. It would be painful to talk about, she knew and she wasn't going to pry if he'd rather not get into the details.
