Merrion/Ari/Drake/Open
Merrion was, in a word, confused by the exchange between Drake and Ari, but before he could ask them about it Ari had already led him to the dance floor, giving him only enough time to set his wine glass down.
He took a moment to recollect what Guy said about posture and hand placement and tentatively did as he had instructed. This was all new to him, and his face was redder than when he'd had to practice on others. Which foot started again, the left or the right? The right, wasn't it? So he moved, and he wasn't sure if he was right or Ari had followed him perfectly to make up for his mistake, though he was inclined to believe the latter, and he ventured the question: "Do you know Drake too?"
Then he stepped on something that was definitely not the dance floor, and he hurriedly exclaimed, "Sorry!" Maybe he should just stick to counting for now.
