Thing is, Bortas is a senior member of staff. What’s the point of climbing the hierarchy if you don’t get extra privileges? Remember, he has “important stuff” to do, and he needs extra access to the simulator to do it.
Remember the Voyager episode, when everyone noticed that incomplete, really cool, holo-novel about a mutiny that occurs on Voyager?
Tuvok: “Ugh. Its not a novel, I wrote that as a tactical simulation to practice for the contingency, should it have occurred.”
Everybody else: “So you routinely plot how to take us out in case of mutiny? With simulated phaser shots, and screams, and blood?”
Tuvok: “Hells, yeah. 'Cause I’m security. Its my job. Look it up.”
Remember, as shown in last season, Alara has the ability to lock out the safeties on the simulator, AND lock the Captain out of overriding her security protocols.
Kelly: “Really, she can lock you out Ed. And you can’t do anything? Really? That’s Union policy?”
Ed: “Yup. I can fire her if she survives. But that’s about it.”
Later this season, John or Yaphit or maybe the new Georgia O’Keeffe inspired alien Lt Urk may well do something unsanctioned with the engines, and that’s kinda their prerogative, because they have the technical know-how, and Ed and Kelly don’t. We’ve already seen that Gordon can fly the Orville anyway he feels like to resolve a mission.
