Poor kid, so focused and, from what it seems, busy, that she doesn't even realize how miffed Faye is. And Faye, given how worried she is about those bad, organic habits, like shelter and eating and if they'll have enough money for what they need, I can get where she's jealous. I just hope it's the beginning of the feeling and Faye has time to begin working through the emotions and the conflict before she gets back to the shop. And hopefully it's a mutual acceptance with Sam realizing how the "focused" attitude comes across.
Sam seems like a good kid, and given her dad and past experiences in the strips, just seems like one of the types that gets engrossed in whatever is holding her current interest and everything else goes out the window, possibly even social Decorum from what this strip shows. Sam likes being there, hanging out with them, and likes Faye and considers her a friend, if she knew how she's making Faye feel, she'll probably feel pretty shitty about it.
I'm wondering if there's a way to leverage Faye and Bubbles skills in with Sam and form a more symbiotic thing. Internal sprays, under the dermal layer, AI and those they tell only know about it, this way it's got a more personal meaning. Modified parts with sprays. Instead of a repair or a spray, how about we replace your whole arm with this claw that has been intricately detailed by Skullmaster... err Spraymaster at this point?
Or, since it seems the sprays are temporary, perhaps Faye and Bubbles coming up with a way to make them a bit more permanent with a clear coat overlay, or a method where you have multiple sprays and a way for them to be changed depending on the wearers mood. But that's more dependent on if part of the appeal of the sprays is the fact that they're not quite permanent.
