Byrne was definitely going to take up Renamon's offer to ask her anything. But there was so much he wanted to know and only so much time before this shift would inevitably end and cut their conversation short; he would need to choose his questions carefully. Or so he would have, had Renamon not made one possibly innocent comment that made him insanely curious:

You're human.

Normally, Byrne could have taken that as a common expression. He was human, therefore he was imperfect and shouldn't expect to immediately understand or cope with everything that was happening here. Which made sense. But the fact that Renamon was saying that, after everything impossible that she'd showed him and this talk about the dimensions she came from... Maybe it was a stretch, but was she possibly alluding to something about herself here?

It was likely discourteous to ask, but she did say he could ask about herself. And so he would. Nervously. He adjusted himself in his seat, clasped his hands together and set them in his lap, and looked at Renamon a little sheepishly. "Well, first of all, I...I-I apologize if this is rude on my part, but I've been wondering and I'd like to know, even if this may or may not relate to what we were just talking about..." He swallowed. This shouldn't be this hard to ask, just ask it.

"Renamon, are you human?"
