To unload even a fraction of his worries on this bright-eyed child would have been cruel, though she in a sense was one of the said concerns. A girl like this should have been preparing for school tomorrow morning, or on some journey around the region pokemon in tow. She shouldn't have been here leagues under the sea in a den of criminals and cheats regardless of how well-intentioned some of them may have been. And so when she waves he can't bring himself to offer a smile, still offering a response, his middle ground.

"That's a way of looking at it I suppose." Seeing the girl wander reminds him to bring up a motion about curfews for underage grunts at the next board meeting, though it was certainly something that'd get laughed out by Chu-e and most of if not all others on the board.

"Your name and station?" He's curter than he intends, a byproduct of his weariness. "The manufactured gardens serve as a better place to wander in the night." An attempt to backpedal, at least somewhat.

His weariness had clearly gotten to him, and the girl notices it. It's in the way he moves, in the way he speaks. How sloppy. He makes a note to sharpen his focus sliding a hand through his hair all the while, an idiosyncrasy he'd developed in college. She emphasizes her name "Robbin" and he plays it back a time or two.

"My apologies, long day, Robbin." And it promised to be an even longer night judging by the looks of his own muddled mind. "I suppose I am for better or for worse." His response to her comment concerning his profession. He cares too little to bring up his own rank or accolades at the moment. As far as the young Ms. Robbin was concerned he was just that some wandering scientist.

She asks what he's doing up, and he has no real answer. His brain was built to spin and spin until it couldn't anymore, and only then was he granted rest. Of course, certain factors were able to work outside the callous machine. Stormy for one always had a way to put the man at ease; one of her many talents and conversations with his longtime ally, Eliz also helped the man find rest following a talk or two.

He relates to her take. As scenic as the gardens could be at times, 'scenic' wasn't always what was needed. Tonight the barren hallways took their place the drab empty blacks and greys of the sub if nothing else helped clear mental space. What it lacked in color and beauty it made up for in emptiness, less to focus on externally meant less to distract internally.

"Aren't we curious." His only response warding the girl's question away. He had yet to come up with an answer and so he had no intention of answering. Thankfully, rattling occurs in the vents above, loud enough to disrupt any flow the conversation had built.

Eyes focus on the shaking and skittering above as the vents lead down a corner. There was no exit, but whatever small pokemon that'd gotten caught in there could cause damage if it wasn't dealt with in some capacity. A task Miles could accomplish.

"I suppose that is why I'm up now." As he begins to walk. He doesn't expect the girl to follow, but if she were he'd have no intent to stop her.
