Darulio was unconsciously giving off pheromones that make people highly aroused, which is a normal biological process of his species, and he doesn't seem to be aware it was happening. From his perspective, he and everyone he had sex with was in their right mind, but extremely horny. And everyone he had sex with gave enthusiastic consent.
But later on, when further asked about why their marriage went wrong, they chalked it up to possibly being the result of Darulio's alien influence, not that Kelly was just hornier than usual.
You can say this is an example of Darulio failing to be aware of alien perspectives on sex, but to say it was rape is a stretch.
That's the same thing as Moclan society. It's not genital mutilation, it's corrective surgery.
I do get that it can be interpreted the way you're saying it. Just like that episode when the extremely hot metamorph was digging Picard. Yeah, it wasn't that she had no agency, metamorphs, male and female just happen to derive actual physical /mental pleasure from making their mates happy. If they were to bond with their mate but then be separated, they would experience some kind of physical pain, or something like that.
I liked Jansen as Kamala, I liked that Picard got a a hottie that wasn't playing him for a fool like Vash, but it ends up being a highly sketchy, indulgence in male-fantasy. Oh, this drop dead gorgeous finds me irresistible just merely because I'm the only guy around? And if she stays around me long enough she'll be virtually incapable of leaving me? And her only source of happiness is to make
me happy? Alright!
Sorry to go off on a rant, but holy crap, Picard's romances have been depicted do poorly.
Anyway, this is an example of The Orville doing some TNG-mash-ups and taking them further, in this case for the worse.
"Naked Now" + "The Perfect Mate." I suppose if it was a commentary criticizing the episode I might look at it differently, but considering these are characters we follow regularly and considering that the show treats issues of religious intolerance and gender/sexuality bigotry seriously, it doesn't make sense to treat rape lightly in order criticize or parody a couple of problematic TNG episodes.
