The access codes and routines to the ARIA had been rewritten long, long ago by one very cheeky, one very idle and one somewhat annoyed Executive Officer. The motivations for doing so were worryingly simple: So he could use the Matriarchy's time and money to play computer games using the network, and to ensure that the Matriarchy gets fed a stream of misinformation about how the ship was being run.
The truth would've scared the crap out of them, and probably had the ship mothballed and everyone detained for questioning. Those motivations aside, Aiesu didn't exactly seem all that forthright about something. Even as a civilian contractor, she was getting wonderfully nosey.
"Don't children usually spend their time catching bugs, or trying to hack into PANTHEON?" Keib commented on her body's appearance first, "Or, better still, pacified by video games rather than poke around where they aren't wanted? This isn't a Yamataian kid-detective story where you solve everything and go home with a big fat reward."
He then looked to the others, "Oh, yes, forgot to say. This is a civilian party interested in the Mok'Ro for some reason or another. She may seem inscrutable but-" He looked over at her. "I can make guesses." He didn't even say her name.
Keib made the 'I AM WATCHING YOU' hand gestures towards her and gave her an upwards nod. His guess was that she was here to evaluate the ship's conduct, and probably bring the truth to the matriarchy - or she was deeply interested in something the Mok'Ro was carrying - and he hoped that it wasn't the same thing that sunk it.
