Eric arched a brow at Sam's comments, but said nothing. He had no idea what he'd done to upset Sam this time. He'd just been making conversation, answering the other man's question. He didn't understand why Vala's choice in clothing had made Sam angry.
To Eric, Sam seemed moody and unpredictable. Eric never knew what to say to him, never knew which comments might piss him off and which ones he would deem acceptable. It was exhausting trying to have a conversation with him.
"I'm sorry to have ruined your night," he finally remarked after a moment or two of silence. "If you will excuse me, my bar stool is looking rather forlorn without me." He turned and left Sam to return to where he'd been sitting when the other man had come in, picking up his abandoned beer and finishing it in one go before signaling the bartender for another.
