So it's some sort of stage outfit, then? Well, that explains one mystery at least. Lucas isn't really familiar with any thespian traditions, especially not foreign ones, so he doesn't really question that particular part of Calen's explanation. Still, there's a few holes in his story that could lead to potentially interesting implications if followed. For instance, even though he just finished his last performance, why aren't other cast members with him? Even if they couldn't party as hard, one would think they'd want to celebrate their final performance together, right? Not to mention...
"Isn't the final performance a big deal, though? What's going on that you have to miss it?" Lucas asks casually as Calen sits down between him and Gram. Now that he was up close, Lucas took a moment to examine the newcomer's appearance with greater scrutiny. From afar, even despite his flashy outfit, Calen looked thin, but calling him that would be an understatement: the guy was down right skeletal! Did he have some sort of eating disorder? Did he need to lose weight for his role? Whatever the reason, his emaciated appearance only served to give Calen a creepy vibe that was hard to shake. That being said, Lucas has a very good poker face and doesn't let any of his thoughts show through his expression.
In the meantime, Lucas inwardly smirks at Gram's response. As a fellow "sit at home" kind of guy, the Hermit can definitely relate to Gram's predicament. If Lucas wasn't currently busying himself with being a nosy older brother, he might've been able to commiserate. As it is, though, Lucas makes a mental note that Gram was indeed trying to meet someone, then continues his current act and comments, "So your date did cancel on you. Tough luck."
"Anyways," he continues, shifting his position to better address both of them, "Like I was telling Gram here, I'm from Mistral and I'm here in Vale for a bit of business. An acquaintance of mine told me this place was good for a quiet drink, so I figured I'd come down and check it out." Lucas stops for minute and looks out to the rest of the bar. "Though, if you ask me, it's a bit too crowded for my taste.
