OK, first: EEEEEEEeeeee Winslow!
Now that
that's out of the way . . . I'm really liking the nuMomo arc so far, her journey and growth as an individual in a new chassis that alters others' perceptions of her. I think the library will be a good fit for her. Momo may still be naive, but she does have that social protocol database in her, so she's not without any clue on interactions. Odds are her experiences will enable her to add some footnotes to that.
I noticed the faded hair color of her old chassis in this strip too -- probably just Jeph's way of signalling to us "nobody home" -- though I'm not sure if there's an equivalent of that for Pintsize and Winslow. I suppose in the context of the strip it could be handwaved as "the hairs are fibers connected to LEDs" or something.
And while Momo lives in a different building from Winslow and Pintsize, there may be other ways of bridging the distance. Maybe Winslow rode a flying Roomba there, or used clotheslines as ziplines, or used a secret underground tunnel, or thumbed (pseudopodded? appendaged?) a ride from someone.
I . . . am very curious about what the hell the "samples" were, but I hav a feeling we'll never find out. Unless the couch dissolves, or becomes sentient, or emits a steady stream of hyper-intelligent ant-men . . . or just has sort of a pine scent for awhile.
