They haven't threaded enough for Ro to figure out why, but Mio pings her "needs help" radar like whoa. As much as she pretends not to care, Ro has a habit of sticking up for people who are way too meek, naive, whatever to stand up for themselves - or she'll try to teach them how. Ro doesn't exactly know why, but Mio reminds her of one of the quiet ones back in the girls' home who was always bullied and singled out as an easy target.

Right now, though, she chalks that impression up to trauma from being formerly dead.
