XIII had stayed quiet for the most part. He just observed and took note of the surroundings. When the sound of a door opening came from the meeting room, he made his way to the room. He took a seat and grabbed one of the cups that Zesiro had brought with him. It smelled like a strong black coffee, but he wouldn't take a sip until he watched the others drink without issue. He didn't trust the place or the yet. 

XIII folded his hands under his chin and watched Zesiro. It was strange that at the current moment, this man was the only one here in a room with possibly dangerous people. There was technically nothing stopping them from overpowering Zesiro and bartering for freedom.  But that didn't mean that he [i]could[/i] be overpowered, and if he took consideration of what John said and that they were actually underwater, they'd be stuck. 

The sound of the door opening drew XIII's gaze away from Zesiro. Out from the doors came Twain, a woman covered in bandages and burn marks, most likely the one Twain helped in the castle, and a woman he hadn't seen before. She grabbed a cup of coffee from Twain and downed the entire thing, and gave what looked like a forced grin to everyone. Twian spoke up and suggested that they get start getting comfortable before asking where the old guy was just before he walked into the meeting room.

XIII continued to stay quiet as he now watched Twain.
