I think it hit "don't really hate each other and semi-care" and kind of stayed there after like episode 3 or episode 5 or something
Some of the conversations and body language are really in line with a mother & daughter and only really started become prominent after Michiko rescued Hatchin from the circus. For example, the Michiko at the start of the show wouldn't have comforted Hatchin the way she did after she met that amnesiac boy. The body language displayed between the two at the start of this episode was absolutely not their near the start of the series.
