This. Her place would be a veritable GOLD MINE to him. Gadgetry and things he could tinker with ohman. IDEK it would have to be his last stop or he would never get to any other place. Seriously I think he'd run the risk of Felicia FINDING HIM there amongst all her gadgets.
Oh the joy of having a natural obsession thanks to his species!
But yes, he will load up what he can manage, probably some half built things or whatever she's created, things he's unfamiliar with or that seem curious to him. If only so he can go home and pick them apart then put them back together and try to make them better (or worse... he likes toying with shit doesn't mean he knows what he's doing exactly, though they are innately BRILLIANT with machines and technology. He's kind of an idiot savant of Omwati I guess.)
That lock, he'll take it, just to spite her. But even if she had installed it there's a good chance he would have gotten through it. He's amazing at locks and LOVES a lock deemed impossible. It's a CHALLENGE he can't ignore.
But in any case. Yes, that and tools. Do want.
He might snag one religious icon and just be like "WTF is this??" strike up casual conversation give her a small clue he was the one that was there, rifling through your junk. I think he may leave her robes unmolested though, he'll be more interested in everything else.
And that report. That can def be taken. He won't damage it, but he will read it to learn what he can about Marina and the other creatures and what not that were there.
Most if not all of these things can be returned of course. The tools he'll be reluctant to give up but her toys (which he'll have tampered with a lot), the report, the religious figure, most of the junk can be given back with a price. >3
