Conversations with murderbot are always a bit of a minefield because occasionally it will drop the most devastating piece of info totally casually and then move on while its human friends are left reeling.
Like one day they're having a watch party or something, and ratthi will look over, stare at murderbot for a second, then say in a surprised voice, "oh, i didn't know that secunits' organic parts age the way humans do!"
Murderbot is quiet for a few seconds as it studies itself from one of its drone cameras, sees the fine wrinkles starting to line the skin of its face. Then it says in a wondering voice, "I didn't know that either. We usually don't live long enough to experience significant changes to our appearance."
And then an explosion happens on the display and murderbot goes back to paying attention to its show while all the humans around it stare at each other in abject horror. Arada's on the verge of tears and wants to hug murderbot so badly. Instead, she just hides her face in Overse's shoulder.
