If Kira wasn't hurt, that was Rei's main concern alleviated, but when she mentioned that he was in fact armed, he glanced to Setzer once more. Everything about the man's appearance suggested someone not only untrustworthy, but dangerous, but Rei wasn't one to be intimidated, and if he'd kept his hands off Kira, he thought that they may as well try to see if they could try to fill in the blanks for one another. Like Kira, he wanted to know what was going on with the girl. "She was normal when she moved... she just won't say anything," he replied.
"Is she okay?" Rei asked Setzer then, letting him in on the conversation then. Setzer realized if these two really did know nothing of Vector, nothing of him, then they'd know nothing of Terra's unusual state. "She's fine," he replied. It all struck Rei as very odd, and maybe it was inappropriate to ask what that thing on her head was-- maybe she had some kind of condition-- he felt like he was missing something considerable. But he decided to prioritize on a matter that concerned them all.
"Kira said you were lost... and make that three. I don't know how I got here."
Setzer frowned. So they would be of no help; what was the point of standing around with them any longer? He doubted Kira would follow him again, now that she was with someone she knew. "I see. Well. Goodbye." He placed a hand on Terra's shoulder then, to have it she would follow him as he turned to leave. He would want to speak with her as well, see if she knew about any of this, but not in the company of others.
"Hold up--Goodbye?" Rei said at this abrupt end, taking a step forward. "Do you know where you're going?"
Setzer looked over his shoulder. He smiled, then, at the younger man's attitude. It was really strange, to him. "How's that your business?"
"If we're all lost, we might as well not split up. And since that girl can't say anything, I don't know how I feel about letting you walk off with her." He didn't mention that Kira had told him that he had a weapon, and it didn't seem like a stretch to naturally assume he wasn't the right type to make such assumptions of.
Setzer, then, turned all the way back to him. Rei addressed him with a familiarity that would of been insulting, was Setzer not the sort who did just the same to others. But then, he was a man who was in the position to, where as Rei appeared to be some average teenager. They weren't quite on equal footing. "She wouldn't respond to you, would she?"
"...No," Rei said, watching him as he waited to see where he was leading that question.
"Terra," Setzer said to her then-- someone who she responded to not just by touch, but by his voice as well, when she was wearing the crown. "Tell him you know who I am." At no point had Setzer felt he couldn't of physically taken care of this other man, if he'd gotten in his way and not let him leave, but he wasn't so eager for violence that he saw it as the first way to solve any issue. This, just as easily, would resolve it.
