Puppeting Marcus a Little Bit.
Feeling rather pleased with how their initial conversation in the lobby had gone, Robert mentally prepared a list of topics he could potentially bring up with Ms. Cassandra en route to the bar. This had the effect of making him fall into silence during the short walk. Luckily, given the fact that she'd have to stop to look at him if he did have anything to say, that was just convenient. He even went so far as to decide that the rest of the evening might actually be pleasant.
That is, until the door to the bar opened without his help, and a six-and-a-half-foot tattooed thug rather drunkenly stumbled out of it. Robert almost instinctively put an arm in front of Cassandra. He didn't actually touch her, or push her back, but it was a protective gesture.
The brute looked him over entirely, looked Cassandra over, and snorted. "Easy, cabrĂ³n. I'm too fucked up for that shit right now. Heh... maybe later, though, I give you and your girlfriend here something to be scared about. If you really want." The teasing tone of voice was apparent in the expression on his scarred face, and he gave them both a knowing smirk before moving past them on his way out.
Rob watched the man leave with wide eyes. Then he cleared his throat, pulling himself together. "Really. The people here." He sighed, and opened the door for the lady to go ahead of him, trying to recover gracefully from the near-altercation with a man who was, in all probability, a base criminal.
