In episode 5 when Major Kusanagi is reviewing the original Laughing Man incident footage in her own apartment, two girls can be seen with her. One bringing over a cocktail and then both unknown girls sleeping near Matoko on the bed.
One appears to be dressed a a maid, and for giving Major her drink I assume she's her personal maid bot.
The other girl's outfit I can't identify. She has dark hair. The maid has brighter colored hair.
Once again in episode 20 we see the bright-haired girl talking to Major while she's preparing to switch bodies. Apparently the body switching procedure requires for a witness. We also know that cloned people cannot inherit real estate. I'm not sure if these factors are connected, but something tells me a bot wouldn't be a legible witness for body switching. Possibly the girls are people, not androids.
Who are these two girls? Are they people or are they androids? What are their names? What are their responsibilities?
