Yeah, it looks like O'Malley is a 'work buddy'. One of the common misconception of these people is that they are friends but they aren't. They're asses who never get off your case but you're not allowed to hit because they're 'jolly' about it and may have some degree of seniority over you.
That aside, it is interesting that, as with Momo, we here have a synthetic with an actual sex drive, of sorts. Yes, she wants companionship but she wants this to include physical intimacy of some kind. Okay, so she is into the misuse of bread products in a big way but, given that robot sex is done by data packet transfer, any physical element to it is going to take on the form of a kink of one sort or another! That's the point here, of course. I don't think O'Malley has the need for an intimate inter-personal relationship (I imagine that's not uncommon amongst Synthetics) whilst Roko does indeed want both a companion and a lover in one package.
I'm really interested to see where Jeph is taking this.
