Gawzarth had accepted the drink from Arrigal at the start of the interaction. But he quickly withdrew from active conversation into a stioc silence. Both because he was still physically and mentally perturbed by the lack of warmth, (for although the tavern was indeed much better than the outside, it still wasn't much beyond a meager improvement) and also because Kealsha was a far better speaker than he. As were the bard and even the rogue. 

Then when a more private meeting was called for, he grudgingly began his way with all the delay he could muster. He got up slowly. He was tired. And he began to stretch his many muscles. He did this for a few moments before regarding the old one who had initially spoken to him with an approving nod of his head. After some more moments passed he finally pulled himself away from that fire and began walking idly towards the booth. 

He looked around the tavern as he dawdled, walking slowly to the moonlit setting arrangement that this Vistani man had pointed out. He appraised the tavern with his senses as he moved through it. He took in as much detail as of his environment as he could. 

He felt the disappearing warmth from the fire behind him. He smelled the scents in the air around him. He took note of the smells of food and drink, of place and person. He turned to look at Lucia Salazar with golden slitted eyes before observing the other patrons and assessing their capabilities. He listened to Kealsha talking so business like as he drew closer. And he tasted the stranger's champagne once again as he entered the booth and sat down  across from Kassandra, who had just sat down before he did.
