Well, of course that's what i take after everything i saw so far, the most logical way i can think of for this kind of set up.
"...She made me as I am, perfect in every way..."
That's what she said! She just told to our face that if she is no good it's the Commander fault for not be able to grow her to be the ultimate weapon as she was design by Mother AI.
"Who'd've though... I'm actually homesick for the underground. Mother sends me here, in harm's way, while you sit and watch me prance around in skimpy outfits from the comfort of your armchair. Hardly seem fair."
As far as i saw this was only thing referent to us how Commander's stations when supervise their Arkana. I can't remember any main+side quests from lv 24 to 28 has any more referent than this. In OB my max girl right now is 25, i Print Screen every dialogs of all Main, Side even Daily quests, nothing get more than this... i have to wait for end of 29 or more to see if their would be keyboard referent mention.
The Commander is sitting on the ~ shape comfort chair, a small stool has water cup and energy bars within hand reach for maximum comfort on long operation time. For 1 on 1 supervise the Commander would not need any monitor. They would just need some thing like google glass may be something looks like Punisher lv 9 helmet, a small goggle with HUD and earpiece speaker and mic for video/audio feed from the Arkana' helmet' camera/mic for communication between them. Those headgear may use wire connection to minimum the wireless radio wave exposure/interference through out the base.
No need for cumbersome hardware like a now day PC. Just voice commands the Arkana, order her to kill this or that. Assist on targets when she's facing crow of enemies?
The headgear may have something like eyes movement tracking (or at least something like AR hand sign recognition) the commander selects the next target(s) from the real-time feed video from their Arkana' helmet camera, the selected target data would be send back to the HUD on the Arkana' helmet, so she doesn't have to chose what to hit next, she'd just hit the target which her dear Commander selected for her on the HUD. If she die, that was her Commander fault at didn't know what to order her to hit when assist her.
For multi Arkana supervise the Commanders would need somewhat a big monitor to show all the Arkana they're supervising.
That is what i vision of that referent.
Now day "we" have something nearly similar to this already minus the assist target selection by eyes movement tracking (or AR hand sign recognition) and the comfort chair on most case, of course it's military application. Don't see why the Commander and Arkana wouldn't have that.
"Although Mother's Law frowns upon mind control, we're increasingly desperate. If we don't think like them, they'll wipe us out. It's is a brutal fact of war that the edge often goes to the side that is willing to do what the other isn't."
"Mind control! Such a thing exists? Abomination.
(And don't even think about it, Commander. I know how your mind work. Controlling mutans for war is one thing, controlling an Arkana for pleasure is another. Try it and die!)"
"You're going to have to come to terms with that reality on your own time. You have an assignment. Slay the Festering Lupis' that have wandered close to Enocia and retrieve the Mind Control Chips implanted in their skulls. I plan to show you fisthand what we're dealing with."
"Your Arkana fingers the Mind Control Chip thoughtfully.
Mind control is nothing short of r4p3, I don't care what it's use for. Forcing someone to do something they otherwise wouldn't. It's like stealing their soul.
Will helping the [Faction name] do this rob me of my soul? Do i even have a soul to lose, or am I just an artificial creation, as I've so often been told?"
So may be sooner or late Mother AI may use direct control by brain interface implant.
