It lingered for a good while on his countenance, that look of earnest apology. In the end, he didn't care to hurt anybody's feelings, mostly because those that he gave such a brunt attitude to were those that didn't seem to have many feelings at all, at least outwardly. And, well, it was true that the silence felt like punishment, as his great strong mantle bows and hunches down, looking away. He even scratched the nape of his neck as an excuse to look away and fill the time in waiting for a reply. This conversation stuff was difficult for him

His whole cloak seems to fall onto him, enough to trace the outlines of his shoulders and back as he slouched forward.

But then, finally, after his eyes really began searching around for an escape... She responded again. Now he turned his head back slowly and met her stare earnest, not buckling to it but in a more sincere and firm way rather than intimidating or aloof. He felt like he was in the clear now especially with her acknowledgement of understanding, and he figured it would be better for himself if he didn't bounce around nervous questions in his head. Thinking was often overrated, anyways, because whenever he did it it just seemed to grip him and not let him go.

All things said, he still did not like that smirk. A tinge of indignation bubbles but then he softens it, realizing that his primal heart was just flaring up over something that likely meant nothing to the woman.

He swallows upon hearing what she said, knowing that there was a degree of mutuality in their presence here. He merely thought it'd be... Stranger for the wealthy looking Drow woman to be in a place like this, that was all. He wanted to say that, but instead what came out was "Yes. That makes a lot of sense when you say it like that." He pauses, the other things he wanted to say running away from that. He merely muses avout nothing "I like that thought. O-of only representing yourself, that is. And no, I am not. You are..." But he couldn't find the word. A horrible embarrassment washes over him, and his expression shows his befuddlement at finding the right word

Oh, she could tell her silence was a powerful tool. The poor fidgeting from the large man was quite the fascinating sight - how much control she could muster over Santiago just by the fluster of words offered. Of course, she hadn't even considered making use of her otherwise secretive magic that lurked from within.

Regardless, Vierna watched with some satisfaction of the relief the lumberjack discovered by her words, ever the worthy sight to behold. Eventually that smirk lessened to a simple smile, a hand reaching to flick casually at her hair while she otherwise chose to listen and see just what Santiago had to say.

Like he mentioned before, there was quite the clear hint that he struggled with his words. There would be moments of acknowledgment with a nod, a curious swirl of her cup until his final fumble. Oh gods, was she curious now.

"..Oh? I struggle with some words too. Not my native tongue, this common language. I'm.. What?" - Vierna questioned simply, a swift move to reassure his worries aswell as that shameless curiousity out in the clear.

Of course the man isn't one to be proud of showing a sign of weakness or an opening to take advantage of, but he inevitably did here and there. His aloofness and brutish "Big stick" Diplomacy in his phsyicality whne push came to shove often prevented him from being controlled or manipulated... Or so he thought. He can't suspect one of magical hyjinxs as he doesn't even know how to recognise it. He really should know better that elven races were inclined to such as a half-wood elf himself... But he wasn't very.../close/...To his racial heritage outside of his natural woodsy-ness.

Santiago does seem to notice the smirk turn into a smile, and it was evident that he liked it better that way, one could tell in his eyes

But yes, words did fail to express the compliment he had about smiling, maybe because his mind didn't think it appropriate at the moment. He goes grave and muttered and mumbles a bit trying to stall for a word as he sees her swirling of the cup stop, but he doesn't go to twiddling his thumbs like before and it instead seemed like something was visibly bothering him, like a fly would have. 

He does seem to appreciate the relatbility appeal instead of judging him for it. He merely nods in agreement, and finds the word after a moment or two desd silence from him since the "Ummm"S and grumbles weren't doing him any favors. He wasn't for useless noise, after all. "You're... Interesting. I didn't think you'd offer to 'start over', because people don't seem to forget and let go even little things sometimes." He didn't want to imply that he had assumed pettiness of her because of her status, and that was the better way of saying it. It was still truthful but not hurtful.
