I think that we've finally found out what Bubbles sees in Faye on a physical level: She's really into things that are soft and warm and cuddly (which pretty much is Faye). After learning to handle Faye's personality there was literally no downside to the relationship!
I love the effort Jeph made to turn Fairy Girl's little noises into a structured language of some sort. It makes me honestly think that she's actually decided to become a fairy down to creating her own way of expressing herself!
It's also wonderfully in-character for Winslow to apologise to Fairy Girl; like Momo, I think he permanently lives in terror of breaching some unspoken social rule and, in his case, maybe getting Hannelore in trouble.
Finally, I'm kind of starting to see the advertising angle here:
Found a Synthetic broken down in the street?
Think it may need fixing?
Then Drag 'Em To...
Union Robotics!
