As Lin came with her response, Dalton felt pleased that there was no hesitation in her words. Perhaps not as eager as he was to continue the conversation, but engaged in it. That was all an enthusiastic wizard could ask for in his conversation partners, so long as he was careful to not get too technical about it and alienate her rather than welcome her in.
Her further playful words had him chuckling, stuttering out a near-bashful, “Ah, well. Yes, of course.” He didn't think he'd ever got asked to show something 'fun,' as most in his old circles were quite stuffy and academic about it. Enthusiastic, of course, but it was all about the details. “I know some little tricks, although you'll have to be the judge.”
As he spoke, Dalton focused his attention and conjured the astral hands, feeling one take over the umbrella as he stepped away, walking a few paces ahead of Lin, backwards as he held his hands up in front of him, grinning.
