They absolutely did not hint at it, in any way. Him being able to use the gear is irrelevant to this question as many humans use the gear without problems as well.

If they really did hint at it they would've had him ask questions in a different way. He wouldn't ask if an Orphenoch could be good in general, he would ask if this particular one is worth trusting since he knows in the back of his head that there's at least one Orphenoch that isn't going around murdering people all the time. This may just be me applying real life logic to something dumb again, but holy shit.

So no, this still isn't making any sense to me as they had to reveal it in such a manner that previous plot points were irrelevant for it to be a surprise, and that's just stupid.

God I can't wait until I'm done with this trainwreck of a show, I hate it so much.
