Kat took another sip of her beer – so kindly payed for by Ernst, she thought with a smirk – when Ehluria walked in and sat down. Looking far too innocent, she replied, "Honestly, I wouldn't know. Maybe he's just tightly wound." But her eyes betrayed her mischief and she hid her smile behind her beer. 

Setting down the empty mug (she'd finally finished off the last drop) she reached into her pocket and pulled out one of her silver coins. Kat began with it placed on top of her fingers, and started maneuvering it across her hand, deftly flipping it over her fingers. Originally she'd taken up this practice to make her left hand more usable after losing the right one, but since then, it'd become something of a habit for her when she was bored or nervous. 

She watched the silver glint over her dark skin. "Not fond of drinking first thing in the morning like the rest of us?" she asked idly, referring to Ehluria's order. Her voice carried a note of sarcasm, as she wasn't actually one for it herself.
